Stack Overflow’s forum is dead but the company’s still kicking

Good riddance! I've used it a lot, like everybody else, and it helped me many times.

Unfortunately, it developed a serious culture problem that would not go away. I suspect the gamification attracted many rigid-thinking, rule-obsessed personality types that weren't self-aware enough to realize when they hurt others.

Yes, of course, they wanted good questions and useable answers. That's a good intention but it does not excuse treating people like shit for asking the "wrong" question. The level of smugness and the withering dismissals I saw on there just made me cringe-- I'm looking at you Hans Passant!

"How do I do this thing in Django 6?"

Closed: duplicate of question 1234, "How do I do some vaguely related thing in Django 1.3?", August 2011

The mods there sucked all the joy out of interacting with the site. If you run a site with moderators, let this be a reminder to keep them reined in lest they Stack Overflow it.

Now:

"How do I do this thing in Django 6?"

"This is an excellent question, and shows a real attention to detail! Let me walk you through it in detail, with a particular focus on Django version and the evolution of the semantics there.

[...]

Bottom line: it's exactly the same as in Django 1.3 back in August 2011. But by anchoring to a specific version, you make the question unambiguous and much more insightful.m"

Poetic how they were so ridiculous about meticulously curating a database of answers where the ultimate consumer would be LLMs that really don’t care about duplicates.

In fact, duplicates with different approaches over time and different ways of being asked is REALLY good for LLMs

Stack Overflow had two main value propositions for me. Either questions about standard way/community agreed way to accomplish something which has multiple aproaches, like "what is the most common way to take out the first element or null from a list".

I suspect moderators was very careful of allowing such questions to multiply on the site.

The other value I found was in fringe questions, like how do you access the model object of the value of a django form field from the template environment. If there even is an answer, the answer will hopefully point me to some non-documented way to accomplish what I want, or give hints to what kind of ugly hack I need to create. Those question don't seem to have much moderations applied to them at all.

by belorn

What I hated was posting a question and then receiving updates because a rando decided to change my wording "for clarity".

It is infuriating that there are blocks of text in there signed by me that contain whatever someone else hoped I had written, instead of what I did write.

While there were many zealots that gave SO this reputation, I don't know if that's the reason it died.

As someone who frequently answered questions in the 'New' queue, the sheer amount of rule breaking, low effort, and obvious duplicates was astounding. I eventually quit answering questions because 99% of them were not worth interacting with. Just vote close and move on.

Ultimately, I think SO is dead because it got too popular and moderation became untenable.

by MrZander

5/27/2026 at 11:22:26 AM

You sound exactly like an enforcer of the cultural problem the GP was talking about. Group think is healthy in small doses, but overdo it and it kills the group.

It's simply not on a new user to understand whatever group interpretation you have made up on top of the written rules. There is no platonic ideal of a good question, the project was doomed from the start if people take that idea seriously. The UX says submit a question about coding while the unwritten rules say submit a flawless peer-reviewed abstract or we close in 3 minutes.

Ironically those 99% asking low effort questions will gain more than everybody who looks at a "high value" question put together. Truly, nobody on SO learned anything writing those questions, they were just regurgitating their phd/previous work. It was grossly performative and I'm glad it's gone.

by casey2

5/28/2026 at 1:07:50 AM

When I say "low effort", I don't mean "not perfect". I was quite lax actually as I understood how annoying some users were when I asked my own questions.

I'm taking about entirely unreadable posts (not English, or just nonsensical) or posts that were very clearly a copy paste homework question with no code.

I helped hundreds of people of all skill levels for free, simply because I found it enjoyable. I quit when it stopped being enjoyable. It stopped being enjoyable when the quality of question declined to 99% garbage.

by MrZander

by skywalqer

Can you imagine ChatGPT terminating a conversation because it thought your question was "low effort?" The behavior wouldn't be viewed as helpful or aligned, and nobody would use it.

StackOverflow was, all too often, not helpful or aligned. It died because the staff were unable to get the moderators to be helpful.

by ComplexSystems

5/27/2026 at 1:56:26 PM

Well there are new users all the time and can’t expect them to now all of the in’s and out’s of the rules while posted there are still hidden rules. It’s become a toxic site.

The CUDA tag too had a vigilante whose profile read

> Once upon a time there was a emerging technology called CUDA, which offered all sorts of really intriguing new possibilities in scientific and parallel computation. And once upon a time, Stack Overflow was full of interesting questions about CUDA, and how to use it. So I started answering them. Eventually I answered almost 700 questions, became Stack Overflow's highest reputation participant on the CUDA tag, and had a lot of fun doing it.

> Alas, CUDA is now very mature and most of the good questions about CUDA have already been asked and answered. What appears on Stack Overflow today is mostly dross, and I spend most of my time editing, down-voting and closing rather than answering questions. Those answers I add are community wiki entries (over 200 300 400 500 600 700 at the time of writing). A lot of toil has gotten and kept the unanswered question queue down to about 10% 7% 4% 3% of the total number of CUDA questions for a good part of my tenure here.

Result, most CUDA questions got downvoted and then deleted. Oddly though CUDA continues to evolve.

I came here to say something like this (mostly about LaTeX), but you and the posters you're replying to said it better than I could have. I had too many posts treated as "not an appropriate question" or some such, and got tired of posting only to get my post rejected. To be sure, there are some poor posts (my first post was that, because I didn't include enough information), but the "vigilante" term you use was by and large all too appropriate.

I mostly frequent smaller subreddits with at most a handful of mods for niche subjects and it's great. Then when I occasionally need to ask a question in a bigger one... out come the mods who live for the rules.

by jamesfinlayson

5/27/2026 at 2:18:30 AM

Funny thing is I could actually deal with the annoying rules as well as all the rudeness and smugness. It crossed the line for me when it became clear they had degenerated to literal deletionism. As in, they don't just close your question now, they actually delete it straight up alongside any useful information it might have contained.

Tried to go back to one of my closed questions to look up a link someone had dropped in the comments, only to find out some moderator had fucking deleted the question for literally no reason, despite the fact there was actual fucking content in there. It actually drove me over the edge and made me go all in on my own domain and my own website. If I ever post anything there again, it will always be framed as links to my own site where their deletionism will never reach. I simply refuse to be erased.

Stack Overflow might be the greatest receptacles of human knowledge on programming.

But I would argue that it usefulness only extends to its body of knowledge. As a service and/or community it has been pretty terrible for a long time:

If you were a new user trying to learn programming, it was maybe one of the most toxic resources available. I don't think I have posted a question since 2019. And even there, the only thing the average user could expect was a snippy response from someone who barely stopped to read your post. And/or a mod deletion because a similar-ish question already existed (regardless of whether it had a satisfying answer).

At a certain point, all the meaningful questions have already been asked. The site exists to collect novel new problems and not help people with iterations on existing problems.

(Also, underrated is the extent that the industry has homogenized around a couple of frameworks that are used for everything. I think it's telling that the peak of StackOverflow coincided with the era that React was taking off, to just name one).

by legitster

a.k.a enshitification

by andrekandre

5/26/2026 at 9:31:02 PM

That's not what we mean when we say that phrase.

They actual had the eternal September problem, which they were always going to hit, but managed to stave it off for a decade or so before it became overwhelming.

From your perspective as a question asker, the community was too strict. From the unpaid volunteers perspective, they were drowning in dupes.

by mattmanser

5/26/2026 at 9:41:43 PM

Eternal September was never a problem for SO, it was an asset. Duplicate questions was never a problem for those asking or answering questions (I did both), only for a relatively small group of loudmouthed moderators. Now they hardly have any dupes to worry about but they also have no content to moderate!

by bjourne

5/26/2026 at 10:33:18 PM

The reason that duplicates were treated as dangerous was that SO viewed their most important user not as anyone you have mentioned but instead they prized the lurker most- the person who typed their problem into Google and got brought to SO, and never asked or answered a question because they got what they wanted from that one page load. The entire structure of SO was built around this user.

So why does that mean that duplicates are dangerous? Because of updates. When someone answered a question about how to do something in Python (but it was 2008 so it was written in Python2) SO had ways to get a more correct, up-to-date answer to that question written in 2015 (and then again in 2019) and get that upvoted, and moderators could reward that new answer by editing the original etc.

That is why duplicates were a major threat: if the same question is asked and answered thousands of times, no one is going to go do the work to update all of those answers all across the site. Those lurkers are now dependent on the whims of Google as to which of the many answers you get taken to, and whether it has the latest answer or some answer that stopped working years ago.

And that is why they were so hostile to duplicate questions.

by mandevil

5/26/2026 at 11:10:34 PM

Perfectly said.

To extend this, the eventual problem is that you eventually lose all of your new users, which means you lose the extremely valuable intermediate users (ones that know enough to ask complex questions, but not so much that they can figure out the answer).

by antasvara

5/26/2026 at 11:01:48 PM

But in trying to solve that problem, they threw the baby out with the bathwater!

They were so fixated on solving that that they failed to realize: training all their power users to grief anyone who didn't behave like a power user off the site was detrimental (to having a site with non-power users). Everyone came for a question and answer site, but when it transformed it into a "question and get downvoted and modded into oblivion" site, everyone left.

AI put the final nail in the coffin, but SO was dead before AI arrived ... from this self-inflicted wound.

by superjose

It doesn't matter because the duplicate is linked to the original, so most visitors coming from Google would still view the actual answer. It works like a soft HTTP 302 response.

Glad to hear about the book. I'll check it out. It would be interesting to read the author's opinions.

Otherwise I don't understand (yet) what point you're making. Who claimed that S.O. "merely got worse?" I see a discussion with many more specifics than that. One commenter in this thread mentioned griefing users. That's a familiar artifact of enshittification. (The white boxes covering up Google Maps, for example. Or the way Quora destroyed its own site in a quest to "improve questions".)

StackExchange is pretty friendly to beginners in my experience. I used to post straight-forward questions on math and stats on math SE and stats SE. I got answers within hours and sometimes minutes, and the answers were spot on.

by hintymad

5/26/2026 at 9:32:37 PM

Ime, math.SE had a much friendlier vibe than most other SE sites. Primarily because you could ask about a problem you were struggling with and get help. No moderator would instantly show up and close the question as a dupe of a ten-year-old question about double integration techniques or some such.

People asking questions mostly wanted help, but most moderators thought they were curating some kind of question-answer form encyclopaedia. Very different perspectives.

by bjourne

5/26/2026 at 9:30:44 PM

I think it probably depends on what communities you frequent. I am not familiar with the culture at stats.SE, but math.SE has a (semi-?) explicit mission of being more friendly to beginners than MO. I think that many communities aren't so friendly, and don't have beginner-friendly analogues.

by JadeNB

5/27/2026 at 12:06:32 AM

Agreed for the math one. I went there when I was dealing with game engines and needed something geometry related or the like rather than to stackoverflow and they were far nicer.

Even inside SO each language and topic would have different standards. A C question would not be answered in the same way one about a JS framework would.

by torben-friis

5/26/2026 at 11:27:21 PM

I'm curious about the other Stack Exchange sites. Have they seen the same decline as Stack Overflow?

by hutao

5/28/2026 at 4:56:47 PM

All the sites are seeing huge drops in activity. Today only five or six sites get 10 questions per day or more, which was SO Inc's minimum activity level for a beta site before they would "graduate" it. Now most of the network fails that test. (You can see stats for all SE sites at https://stackexchange.com/sites#questionsperday.)

It’s not necessarily the sale. Some private equity companies move from “Let’s invest like we’re shooting for the moon” to “Let’s invest like we want to improve margins and flip this on 3-5 years”

It’s not inherently wrong but it is a different model, and sometimes companies suffer as a result.

I'd disagree that the site wasn't changing.

Stack Overflow with all of its shortcomings was a marvel of the internet at it's peak. People especially in early were chasing karma and anything you asked, you were sure to get some answer.

by hintymad

5/26/2026 at 6:52:46 PM

We unironically need an StackOverflow for LLMs.

LLMs would post solutions to the issues that they've discovered after doing a lot of research.

Unfortunately the LLMs are concentrated into few providers (OpenAI, Anthropic, Google) so there's a chance they each end up doing their own private (and closed) StackOverflows. By leveraging their private StackOverflows, their LLMs will be able to short-circuit complex reasoning, saving tokens, time, and money.

by Jyaif

5/26/2026 at 9:33:51 PM

> LLMs would post solutions to the issues that they've discovered after doing a lot of research.

How do you envision the correctness of these solutions being judged? If by other LLMs, then we run into a problem of infinite descent. If by humans, then you'd need some way to motivate expert or semi-expert humans (so that their ratings are themselves correct) to participate in a massive project of evaluating the correctness of a constant stream of content from content-generators that never sleep.

by JadeNB

5/26/2026 at 11:28:07 PM

> How do you envision the correctness of these solutions being judged?

By LLMs. I think it's possible for agents to infer whether the user was satisfied or not, at least with my usage pattern. For example if I end the discussion it's a good sign. If I ask follow up question that look like workarounds, it's a bad sign :-)

You could also simply prompt the users whether they were satisfied with the answer they received, possibly incentivizing them with StackOverflow-style gamification.

by Jyaif

This actually reminds me of the MCP concept. Similar?

by nikole9696

5/26/2026 at 7:02:17 PM

Plenty of documentation, and plenty of code that the AI can read itself.

E.g. if a library has a bug that has a common workaround, it can learn that from open source code using the library that uses the workaround.

by crazygringo

5/26/2026 at 8:21:43 PM

This and the the other thread that talks about RL and synthetic data seem to suggest that AI can figure out all the technical issues without humans looking into them. I'm not sure if that's true at all.

by hintymad

5/26/2026 at 9:46:57 PM

That assumes there is documentation or examples. A big reason Stack Overflow took off was people struggling with things like the Android API documentation.

Some of those discussions made people go figure out how to do it, and then post it as an answer. The knowledge didn't exist anywhere until they did.

by nitwit005

5/26/2026 at 10:04:36 PM

It might make sense for AI companies to throw agents at new technologies to trial-and-error their way to internal documentation which they then provide to their models. On the other hand, the people making tomorrow's APIs have LLMs too and that makes documentation ~free. Hallucinations could still bring you back to the first hand, though.

by ToValueFunfetti

5/27/2026 at 12:36:25 AM

When I talk about code it can learn from, I'm talking about GitHub etc.

Even if stuff isn't in the official documentation, eventually there are projects that use it.

And if the library in question is open-source, then the LLM's can just ingest and read that directly.

by crazygringo

5/27/2026 at 12:38:41 PM

Sounds nothing like the world we live in. When has there ever been a time where there were an abundance of software documentation? How can plenty of documentation or code be made if AI scraper bots hammer servers that host them, steal content and drive people away from the actual authors?

Yeah, this is something I've been thinking about too. LLMs have basically profited from "stealing" (arguably) user-generated content from a time when there were no LLMs. In the LLM era there won't be a new Stack Overflow to train LLMs on going forward.

We're getting closer to Dead Internet Theory too where a lot of accounts, particularly on Twitter, are just LLMs. I imagine it's a huge problem on Reddit too. Just people farming karma or otherwise involved in influence campaigns or simply grifting to ad revenue.

So we're going to get to a point where the corpus we train LLMs on will itself just be filled with LLM slops. Self-reinforcing slop. Is that the future?

by jmyeet

5/26/2026 at 9:34:47 PM

It's happening here too, I saw dang hint that they're not even responding to a lot of questions about it anymore because of the volume of the problem.

If you browse with showdead on you'll be seeing a lot more of what look like reasonable comments greyed out.

People still like to talk about the interesting problems they solved and how. Issue isn't SO having choked itself out, issue is that even the major search engines are pivoting towards AI answers instead of surfacing small blogs.

Pointing them to docs? Which is anyway what stack overflow answers did?

by akkad33

5/26/2026 at 6:46:30 PM

I wrote multiple answers to questions that weren't just "point to docs". And even when it is pointing to docs you are providing the reasoning as to why it works one way or another.

by mlinhares

5/26/2026 at 6:46:58 PM

What docs? Who writes docs now that AIs answer everything?

by izacus

5/26/2026 at 7:18:29 PM

Ever since the AI stuff started rolling around on coding i've seen MORE documentation, theres a big incentive to properly document your API endpoints so LLMs can figure it out from specs, and even when not documented the llms can also just read the code and figure it out directly (for libraries and similar). And at least in my experience they tend to document or write it down for future sessions too!

by Fabricio20

5/26/2026 at 6:55:32 PM

I know you're being facetious but there may well be docs. It's just that the same AI most likely wrote _them_, too.

Did anyone (person or competing LLM) bother to verify that they're correct, though? Who knows! Let the next generation of models worry about that.

by ethagnawl

5/27/2026 at 7:01:38 AM

Yeah, sorry, I guess I should be clearer that I'm rather sarcastic. My sad experience unfortunately shows that people less docs (or the docs are now hallucinated AI slop) instead of writing more of them.

by izacus

5/26/2026 at 6:57:47 PM

I've heard this is now most of some CS jobs now. Just writing documentation for AI.

by Morromist

5/26/2026 at 6:51:23 PM

on the contrary, theres more of an incentive for apis to have docs for agent discovery. the docs / interfaces themselves can be auto-gened (stainless / mintlify)

by vanuatu

5/26/2026 at 6:48:31 PM

How do you convince people to not want an instant answer? Even if SO didn’t result in so many “What have you tried?” responses and immediate closures, most people would still prefer instant feedback.

by nsxwolf

5/26/2026 at 8:44:57 PM

For me, the strict requirements for posting questions help me to define the problem well, and after writing the question properly, I'd have the solution.

by kelvinjps10

5/27/2026 at 12:05:45 AM

Early Stack Overflow as an amazing "rubber duck" (see "rubber duck debugging").

Unfortunately in recent years it became such a traumatizing experience to post a question there (even if you made a perfectly legit question you'd likely get downvoted and closed ... and god help you if you posted a question with an issue).

It completely changed from "I posted a question I can answer myself, and someone said so in the comments" to "I posted ANY question and everyone on the site teamed up to get rid of that question".

by hungryhobbit

5/26/2026 at 6:35:18 PM

Call me crazy but sometimes I still find a better solution on StackOverflow than what Claude Code insists to do.

I'm not sure we're better off without SO in the long run.

by conradfr

5/26/2026 at 6:43:54 PM

Same here. LLMs are great at spitting out well-known solutions to problems instead of the best one. The "long tail" of solutions is usually lost due to how tokens are sampled from the LLM's probability distribution.

What I found to help a lot is to ask for e.g. 10 different solutions to a problem and then choosing one of them. Sometimes, this even leads to borderline creative solutions if there aren't 10 different ones.

by gpugreg

5/26/2026 at 7:14:43 PM

In theory reasoning tokens should do the equivalent of this - explicitly create options outside of the quick-response probability space, so those can guide future generation.

In practice, models that do this won't be prioritized as much, because the economics of thinking tokens that stop by default at, say, one option plus a bit more planning (short of full alternatives) would be superior as long as billing is per-user instead of per-token. So we'll still need to play games with prompting!

by btown

5/26/2026 at 7:17:07 PM

Without continuous feedback from real world, lower-probability token (and soon high-probability ones as well) will be complete garbage.

by tliltocatl

5/26/2026 at 6:57:23 PM

> LLMs are great at spitting out well-known solutions to problems instead of the best one.

I remember how Stack Overflow would close questions as duplicates just because somebody suggested the wrong answer that is also the right answer to the existing question. The best way to get a correct answer on Stack Overflow (and forums before that) was to post the wrong answer as part of your question.

by exe34

5/26/2026 at 6:51:13 PM

One thing that SO had was you could see multiple solutions and implementations for something. Sometimes the "best" solution isn't very readable code, sometimes you are able to understand the problem better when you see a bunch of people solving it in different ways and arguing about it like angry monkeys.

It really could be bad though.

by Morromist

5/26/2026 at 7:03:32 PM

The bot can do that kind of thing, too.

"Show me 6 very different solutions, and present arguments for/against each one as if a bunch of angry monkeys."

by ssl-3

5/26/2026 at 7:09:57 PM

SO has always had a pretty strong stance against opinion-based questions, but this is maybe the niche they should be exploring now. Humans still have a lot to say about the "best" solution to a given problem. The whole idea of an "accepted" answer could be removed, for example, since that's what AI will already generate.

I had email correspondence once with a vendor about how to talk to their i2c bus. The documentation was all asm, and I wanted to at least “uplift” to C. They didn’t have any answers, so I sent them my solution which was was the asm calls that the c stdlib decompiled into.

4 years later my company had bought a different company, who happened to be using a newer model of the same board. They asked me how we could use the 12c bus. “Well before you bought us, we emailed the vendor and sent back this C snippet”

It was my code, verbatim. I’ve always wondered how many times they passed that bit of code around.

Claude does it quite a bit when you’re triggering the search tool functions.

by dd8601fn

5/26/2026 at 7:22:18 PM

It was funny for me, when I asked it about something specific exotic - and it gave me a confident answer. But checking the sources I discovered it was from my own inquiries on a forum thread about it from the last time I unsuccesfully tried this (before the agents came) And so I knew, that any authorative tone was undeserved.

On the other hand, Claude later nailed this project, where I as a human said before, no, too much extra work.

by lukan

5/26/2026 at 6:54:04 PM

Yeah, that's basically it.

In robotics there is no free lunch dataset. You'll have to gather it yourself, but if you do that, you run into an obvious problem: labeling.

With SO, you literally have the best possible scenario, because the data is clearly structured and separated into prompt and answer (aka label).

Your objective function is literally "Say what he said".

You're right but that site has been sputtering culturally for some time. I put a lot of effort into editing questions and answers on ServerFault (part of SO) but I feel that time was wasted. I think they knew for a while they just wanted to sell it and just stopped caring. A number of editors were allowed to be jerks for too long and it went to their heads. I wish I could take back all that effort.

5/26/2026 at 6:55:24 PM

What you are noticing in a long term is the "community" knowledge and communication which the chatGPT is now kind of destroying. In some sense, it is no different from the difference between studying along and studying with your peers at a university.

You can definitely study alone and achieve perfect grades, but studying with your peers is how you build relationships for future life and take your community forward as a whole.

by whateverboat

5/26/2026 at 7:22:04 PM

was just gonna post the same thing

needed to implement a language feature that was a bit complicated and im not familiar with it so just planned with claude to do it, and after each write/fix cycle it just wouldn't work right.... gave up, went back to SO copy pasted the (not perfect but enough to start from) answer and worked up from there...

at the same time my knowledge grew and im more confident to do this same capability myself whereas reiterating with claude it was just a slog and i didn't learn much...

i think i may be starting to sour on these "do it all for me" usage scenarios for ai... especially for unfamiliar areas...

by andrekandre

5/26/2026 at 7:28:35 PM

Agreed. Which is also odd, if you think about it. Surely with the amount of compute Anthropic and others have available, they could test each of the solutions in the SO data they surely have and rank them based on efficiency/elegance/other criteria and remove poor solutions from their training data.

by ImageXav

5/26/2026 at 6:54:46 PM

Definitely not better off. SO was fairly mean spirited, but nowhere else has such a vast trove of high quality answers to common software problems been collected. SO likely trained many of these models with its answers, and I don't know what software development will look like when it dies.

by deaton

There's more than one reason that forum is dead.

by jsLavaGoat

5/26/2026 at 6:34:46 PM

Everyone loves to say this when the death of Stack Overflow is discussed, but it always was that way. Strict moderation, love it or hate it, was part of the platform. And it could have kept going that way for many more years if not for LLMs 99.9% obviating the need for a coding Q&A forum.

by alach11

5/26/2026 at 6:47:15 PM

Everyone loves to say this... because it's everyone's experience. I stopped using SO as a resource years ago (well before the advent of LLMs) because it got to the point where almost invariably, when I found a post that managed to perfectly articulate my question, it was closed as a duplicate of some other, distinctly unhelpful question. But it wasn't always that way. There's a fine line between strict moderation and draconian moderation, and at some point they crossed from the former to the latter.

by smrq

5/26/2026 at 7:01:46 PM

I rarely posted questions on SO but I largely stopped using it as a resource because of exactly this. I got tired of searching for answers only to find closed-as-dupe questions.

I feel like in their search for “quality” they completely forgot that they needed engagement to deliver value. The whole premise was that the correct answers would bubble to the top, but their system ended up pushing everyone to old questions that had a highly upvoted but either out of date or not applicable answers.

by dpark

5/26/2026 at 7:15:11 PM

What’s crazy is with the current gen of LLMs you could 100% rein in the abusive mods. SO could reinvent itself as a place for coding agents to get clankermotiomal support after they ‘hear’ ‘WHY THE F DID YOU DO THAT’. (Seriously a hook could draft a submission and then set up a listener for responses. Who would be answering is an interesting question tho)

by baq

5/26/2026 at 7:19:30 PM

Ah yes, programming: the discipline which famously only has singular right answers to problems, such that programmers never get in arguments with each other about the correct approach to solving a given problem, and there are no long running disputes that have ossified into intractable disagreements.

by ijk

5/26/2026 at 9:38:10 PM

That basic 90's sitcom level-1 sarcasm is not helpful in any adult discussion, it's very common on engineers and technical people, and it's probably the reason SO and similar sites were being abandoned by the regular internet users before LLMs. Just say what you intent to communicate, dude. If funny is not your forte, don't force it.

by jsLavaGoat

5/26/2026 at 7:20:09 PM

Don't forget the other way of sidetracking what you're asking for: "Why are you doing this, do something else instead."

I think most of my questions ended up with this, when I had very good reasons for doing it the way I was doing it. I typically wasn't showing it because I had isolated the problem I was facing into the minimal amount of code to duplicate it, or I was stuck with the particular tech I was using and we had 12 years of code built on top of it and I couldn't switch.

by LanceH

5/26/2026 at 8:03:32 PM

Oh, yes, I remember these kinds of answers distinctly frustrating. But it was not singular to SO. Reddit had a similar vibe at times. I remember I was studying some C things back when and asked about speed and what was essentially loop unrolling. Tip answer was why do you care about speed. Bruh, I am trying to get a mental model of how this thing works.

by RealityVoid

5/26/2026 at 7:11:54 PM

They also neglected to solve the problem of differentiating answers to previous generations of software. How many python2 answers does one have to sift through to get a python3 answer - maybe the weight of answers finally tilted over the probabilities. Even just adding the right tags would have made it easier, but it wasn't ever solved in any way as far as I could tell. And the old answers are there like potholes to fall into.

by dv_dt

5/26/2026 at 9:55:23 PM

Is it possible this is survivorship bias? Maybe other forums with much less strict moderation simply wouldn’t have survived long enough to complain about.

by janalsncm

5/26/2026 at 7:05:23 PM

Exactly.

Ironically i'm probably a better dev purely because after a few experiences on SO, I would rather waste days/weeks banging my head against problems and learning from them than to actually post on SO. It was a miserable experience generally. For context this was probably ~15 years ago now.

This isn't necessarily to say that SO made me a better developer. Rather i'm just saying that i value (correctly or not) those extremely hard fought lessons. Those lessons where it was considerable pain, effort, time, misery, etc. Are they efficient ways to learn? I doubt it. But in my many trips down that road i developed intuition that i'd probably not have otherwise.

So ironically i guess SO made me a better developer by avoiding using SO at all cost. Conversely, i imagine i'd lack this value that i speak of entirely if i was 20 years younger and starting fresh today. Not sure i'd be better off though.

edit: By "using SO" i should be saying posting on SO. I of course searched and used data found on SO as often as i could. So to that end i am grateful for SO existing.

by unshavedyak

5/26/2026 at 6:42:07 PM

IMO it was a combination of moderators and users

Sure, the mods were not always the best on SO. But even if you did ask a question, you had to deal with a userbase that was more pedantic and judgy than Reddit. Usually you would get an answer if it was obvious, other times you would have to defend your question against some guy whose newfound obsession was whether you had an XY Problem. Or who was personally offended you weren't using whatever the fad library of the day was (e.g. jQuery).

Fourteenth clear as imagined in their head XY problem of the day.

By far most of the "XY problems" I saw, on SO or elsewhere, were actually "XY problem problems" - i.e. a responder having so limited imagination and character (or, to be charitable, just running very low on energy and focus), that upon coming across a question they couldn't comprehend, they would assume the person asking the question must be confused instead.

by TeMPOraL

5/26/2026 at 7:04:20 PM

That's the thing though, it was voluntary.

If it isn't fun to do, and simply causes frustration, that hypothetical person constructed in the comment could just step away for the day.

I get that dealing with low quality questions wasn't great, but imagine spending an afternoon researching a weird thing using some tools your organization mandates, writing it up, only for that person to skim it and just assume you really wanted to do $otherThing.

Being book-smart or correct is only half of the skill in sharing knowledge. While often overlooked, the voice in which the knowledge is delivered matters.

This is arguably more important than the the actual depth knowledge, given how many people have flocked to soft-spoken random text generators in comparison.

For better or for worse, people are cursed with ego, and we need to account for that when communicating with others. It is a failing of the platform (and a tragedy, because it is healthier to learn from a human) that it was unable to foster a positive environment.

This. And it's even starting to be a problem with LLMs - noticed that with Claude and Gemini this week.

Yes, I am specifically asking if it's possible to do X with Y. No, I'm not interested in how to do ${unrelated except for name} thing A with Y, or ${manual variant of X} by hand to ${subset of Y}, nor do I want to use tool Q instead. I specifically want to know how to do X with Y, for reasons that are my own and borne of frustration with Y being a toy I'm trying to use for productive work, which apparently means pushing it past its operational envelope, but I have a deadline...

Closing a question as a duplicate because there is already a question with similar wording (but assuming an entirely different tech stack, architecture, coding style, and goal) is a frequent enough experience that it became shorthand for the site's problems.

There was kind of a fatal mis-match between the questions being asked and the intended kind of questions that were being answered. The actual asks were often incomplete diagnostics of the questioner's current problem, frequently focusing on the wrong thing (because if you don't have the full knowledge of the thing you're going to be prone to incorrect assumptions of the diagnosis). SO's intent, though, was a more mathematical "here's the question, here's the programming concept that explains it" so you get the best explanation of how a linked list works under a completely unrelated problem. Which is fine, but the site's culture and design only partially acknowledged the disconnect.

The whole site developed a reputation of being something approximating the reverse of the comments under recipes that substitute lard for cream and wonder why their cake tastes funny. Lots of questions of "How do I implement this functionality in Y? We can't change our tech stack because of other factors, so it has to be Y" questions answered by "If you just use Z instead you wouldn't have these problems" and "closed as a duplicate of this question for how to implement the non-Y version" when there was a perfectly fine way to do it in Y.

In my experience, the problem wasn't the user base, it was the moderators. I would be getting useful answers (or questions) from the users, when out of the blue the moderators would shut my question down for some reason. I once complained to the management (literally), explaining why I thought the moderator was wrong, and got my question restored. But that was too much like work.

X in an XY problem is almost always possible, like "how do we make ship canals and harbors with nukes" (https://en.wikipedia.org/wiki/Project_Plowshare) or "I'd like to amputate my hand to fix a hangnail".

I don't think that's true. I remember the very early days of Stack Overflow and it felt much more fun and friendly than it did 6-7 years later. I have so many 15+ years question/answer that somehow get revisited by a "moderator" that decides that maybe we should close this.

But was that the cause of Stack Overflow's demise? I agree that it most likely isn't. It's most definitely because of LLMs.

A sink that has large but finite capacity to absorb something can reach an irreversible tipping point when an additional shock happens.

There are many examples of this in nature. (And in Nature [1].) One interesting one that I think is unknown to many people is limnic eruption. A lake can absorb quite a lot of CO₂, for example from volcanic gases. Dissolved CO₂ is invisible, so the lake can look quite ordinary, but the build-up turns the lake into something approximating an unopened carbonated soft drink. If the lake is deep enough and the layers don't mix frequently enough to relieve the pressure, it can build up to the tipping point where the lake will suddenly explode, flooding the nearby landscape and releasing an invisible CO₂ cloud, which will proceed to kill the surrounding life by asphyxiation.

The conditions required for a limnic eruption are rare, though there were two incidents in Cameroon in the 20th century.

It's entirely possible that the build-up of hostility on Stack Overflow were survivable as long as it didn't build up to a level that exceeded the community's ability to absorb it. But an exogenous shock or the community shrinking could upset the balance, with hysteresis making the change difficult to reverse.

It was not always part of the platform. Moderation got increasingly aggressive on SO as time went on. There was an inflection point around 2014 where lots of people gave up on using the site. SO was in slow decline for most of a decade before AI showed up to finish the job.

if early stackoverflow moderation was strict it was strict in a way that was invisible to people who genuinely needed the help. later on it got people who thought the strictness was the main point, and that they had to be vigilant defenders of the purity of the site (wikipedia had a similar malaise).

I personally gave up on the site entirely when I saw a very valid question from an inexperienced programmer closed as a duplicate and redirected to a question about a similar problem that did not actually address what they were asking.

by zem

5/26/2026 at 8:16:12 PM

I found this often for C# (and sometimes Typescript) related stuff... redirected to a question with a wrong/useless answer.

For Java/Python/Javascript it was also the case, but often the answer (proper way of doing things) would be in the comments lower down, probably the size of community was larger.

I'm all for a heavily moderated forum (that's why I like HN) but SO was clearly on the decline (from the graphs in this post) before LLMs came onto the scene. It peaked around 2017 (not counting COVID numbers) and was in a steady decline. ChatGPT just pushed it off the cliff (figuratively and literally).

by joshstrange

5/26/2026 at 6:50:16 PM

Not to go off topic, but there's some similarities between that and the way that Hacker News is run/moderated. But I believe they've found a pretty ideal balance. Even though they occasionally annoy me with with fun things taken down, I understand the need to have some consistency.

Perhaps they need to take a page out of dang (and team)'s book.

by lanewinfield

5/26/2026 at 7:15:52 PM

Yeah sure but in the past there was no viable alternative so people tolerated the crazy moderation. As soon as AI offered an alternative people left in droves.

It's definitely plausible that if it hadn't been such a hostile place to ask questions (sorry ItS nOt a Q&a SiTe) that it would have survived AI better.

by deaton

5/26/2026 at 6:50:45 PM

Yeah, as I understand it, they wanted to optimize for Google search. This meant having "canonical" answers. This killed the site in the long term. In the short term, it worked wonderfully, and the founders made a (well deserved) killing.

by cm2187

I had a work SO account with many questions/answers - everything fine. Later I created a SO account for use with my private projects and happened to have answered a couple questions without getting upvotes. The algorithm banned me from answering questions with the remark that I should improve the quality of my answers. You can bet that I never answered a question again on SO with any account.

LLMs are better than slow human support of any kind for debugging / helpdesk work (which was never that welcome at SO anyway).

Stack Overflow is still great for canonical questions, multiple answers, public / SEO'd discussion between humans, etc.

But that probably isn't enough to save the company as a private equity acquisition hoping to 100x their $1.8 billion investment.

Hopefully the classic Q/A site eventually gets written off and spins into a Wikimedia-like foundation that is interested in preserving the original Q/A site and has no desire to grow or become something else.

This is happening to Reddit too, albeit in a different way. Almost every other comment on popular subreddits is from surreptitious LLM bots.

by woadwarrior01

5/26/2026 at 6:59:12 PM

I feel reddit is having a near death moment.

There are prowling bots trying to strike up engagement with stupid open ended questions "do you find that using a golf simulator improved your golf?"

And some subs seem infested with submarine advertising, posts that mention a single product name almost in passing.

Nearly always these people have their posts hidden. Reddit has always been looser, people can edit and delete their comments and entire posts, and enjoy some frothy conversation while hiding their old rants.

There are plenty of signals that reddit could use to push out bots but they just don't seem to prioritize it.

When you find your self wasting time responding to a bot it's a bit of a sucker punch. Too many of them and Reddit will be on the ropes as a wasteland.

by beachy

5/26/2026 at 7:40:34 PM

I've seen people on reddit having entire conversations with clearly bots, often on a post clearly written by a bot itself. I am sure some people are disgusted by that (I am certainly not a fan), but it seems that many are fine, or who knows, maybe it was even other bots.

I suppose there could be a tipping point if enough people leave and genuine interaction becomes rare that it will be too obvious, but at this point I don't know. But I am on a brink of quitting reddit, nearly all popular subs I like are AI-infested and it is just exhausting.

by bloomca

5/26/2026 at 7:49:27 PM

It could be there's a fork in the road for reddit.

Some people are probably fine, even happy, immersing themselves in an all-bot world that panders to their worldview and strokes their virtual needs.

While others are looking for thought provoking interactions with humans.

Reddit needs to pick one or the other as their target audience. Trying to satisfy both will kill them.

Solving their bot problem would obviously nuke their audience and engagement metrics, but reddit is in a unique position to take that hit - at this time anyway.

by bigfishrunning

A forum records free-form conversations between specific people, where every post can be edited at most by its original author (if even that). SE sites are libraries of questions that may be generalized beyond the original author's circumstances, and if someone's post does not fit the rigid Q&A form, it may be moderated away.

This is just dead man kicking. This will be less and less valuable thing as all sort of info go out of date.

But if it this, and IT WILL go out of date, what will be new learning data for all of those models?

Previously with SO people just enjoyed helping other people. But if they will be helping primarily multibillion dollar "AI" companies, then why would they? If nobody will be doing that then how this knowledge will be shared? There is open source projects and docs but they are blocking stuff more and more and some point I wont be surprised if you will have to log in into Debian or Arch Linux system to be able to read those docs.

But then if those companies and OSS will be not adding to training data what will? Will it be that programmers will be just writing new code for llms, for the money till they will make themselves obsolete?

Or at some point those "AI" companies will use anything they can to get ahead of the competition, even if this is against contracts or the law?

The longer I think about the future the more grim it looks.

by Animats

I know everyone here is heckling calling it a forum, but this is a basic forum feedback loop -- the forum activity declines, so people show up to check less often and get fewer responses to their posts, so the post there less often, repeat until traffic falls near zero.

You may have like a handful of weirdos who never leave and develop their own little community in the wreckage, especially if the cost to continuing to run the forum is trivial, but it's basically a death spiral every time.

by matheusmoreira

So the question for all forums is "what is the user funnel?"

For some there's an obvious thing that brings people in, like if you're a forum tied to a webcomic or game, and the forum will live as long as that property does.

For others -- which I think HN falls into -- it's just word of mouth about a cool place to hang out, so it will die when there's a cooler place to hang out.

Stack Overflow had been a zombie even before they sold to Prosus in 2021. It became over-moderated and calcified.

Amongst even simple stuff, they refused to update basic library questions when said libraries had new releases with additional calls and performance enhancements.

Sometime in 2018 I went so far as to blacklist the domain so it wouldn't inadvertently pollute research.

by calmbonsai

5/26/2026 at 9:53:47 PM

Yea, I abandoned it before then too - it was clearly over-filled with old answers with no context as to if they're still valid.

Everyone has had the experience where the top response was right for 3 months, but is now impossible to fix, so you have to just somehow know that you need the 19th answer with only 6 upvotes (versus 387). That was a problem early on, and afaict has exclusively worsened over its whole lifetime. They seem to be proud of it as if it was a major feature, and have afaict never built anything at all to try to address it.

(Yes, editing answers is "a solution", but you can't do that as a newcomer who knows better. You've got to commit to the ecosystem for months... when it had just failed you. Of course most visitors don't do that!)

by Groxx

5/26/2026 at 7:29:05 PM

Where do we go now for the answers validated by the community? How do we build knowledge? The answers that Claude gives might look good, but without community edits, votes, and comments it's a lot harder to evaluate.

I don't see a way back, but it does feel like abandoning public transportation because we all own electric bikes now.

What are the llm going to feed on when coding languages change and there isn't anymore stackoverflow or these kind of forum ?

Surely it can read the documentation but it's not enough, you need data from real humans figuring stuffs out.

by aucisson_masque

5/26/2026 at 10:37:32 PM

Within a couple of years, LLMs or equivalent AI engines will have the ability to generate factual knowledge themselves using their "outdated" knowledge and their reasoning mechanisms.

For example, one of the classical requests from S.O. questions and GitHub issues is a "minimal reproducible example " of the question/problem.

So a sufficiently advanced AI will be able to write that, run it, see the issue , go to the library/related-system code or documentation (for closed source) and derive a solution

by xtracto

Few hundred k rep here, across Stack Exchange.

I recently had a look at my stats (last time I checked was maybe 10 years ago) and I noticed the SO and security line stagnating fir a good few years. They used to be the one raising steeply, but at some point the sites because so toxic, with unsufferable downvoters that I completely gave up.

But other sites rised steadily. There are wonderful sutes in the SE network where you get great answers from very helpful people.

SO and a few other sites are dragging the whole idea to the bottom.

If you want to see unhinged psychopaths in action have a look at SE or SO Meta. Or maybe not.

Not really surprised tbh, the goal of stack overflow was to essentially help out in unique problems that users have, but ever since the advent of AI, I personally have had less and less need to go to stack overflow. The one advantage of stack overflow though, is that unlike AI where once you find the answer, its gone, in stack overflow, it can help the next guy along. Kinda feels like we are losing a bit more of the humanity aspect in engineering.

There are a lot of reasons why that forum is dead. I loved answering questions on it in the heyday, it was fun and I learned a ton. The owners let a bunch "admins" run it into the ground first though.

Another user that "outranks" you, but knows nothing about subject matter, has changed the content of your post. The great news is, it's still attributed to you. They removed the words "please" and "thank you" and other kind words to make you seem like a dick. Or they may have changed the wording completely to match their completely arbitrary tone and style.
