Wikipedia 10K Redux by Reagle from Starling archive. Bugs abound!!!
A wiki is a collection of interlinked web pages, each of which anyone can visit and edit. You can even edit ''this'' page; just click "Edit text of this page" below. So it's a collaborative website, constantly expanding as new people add pages about their interests, comment on old pages, etc. The original wiki http://c2.com/cgi/wiki might give you an idea of ''one'' way a fully-developed wiki might look.
