I agree and I'm guilty of creating what is effectively a heavily hyperlinked knowledgebase and calling it a wiki. Unfortunately, only a tiny majority will ever create or edit a page despite the incredibly low barrier of a web browser without minimal authentication.From Ward Cunningham himself:
"A wiki invites all users—not just experts—to edit any page or to create new pages within the wiki website, using only a standard 'plain-vanilla' Web browser without any extra add-ons."
"A wiki is not a carefully crafted site created by experts and professional writers and designed for casual visitors. Instead, it seeks to involve the typical visitor/user in an ongoing process of creation and collaboration that constantly changes the website landscape."

Wikipedia is effectively a crafted site that is maintained by experts (or at the very least very knowledgeable amateurs who 'own' certain domains) designed for casual visitors. The idea of a Wiki is great but in practice I'm less confident it exists as envisioned.
