What's a Wiki
Wiki Wiki Web is an "open-editing" system where the emphasis is on the authoring and collaboration of documents rather than the simple browsing or viewing of them. The name "wiki" is based on the Hawaiian term "wiki wiki", meaning "quick" or "super-fast". The basic concept of a Wiki Wiki Web (or "wiki") is that (almost) anyone can edit any page. While at first this sounds like a recipe for complete anarchy, the truth is that sites using this system have developed surprisingly complex and rich communities for online collaboration and communication. Yes, it's possible for someone to go and destroy everything on a page, but it doesn't seem to happen often. And, many systems (including this one) have built-in mechanisms to restore content that has been defaced or destroyed.
The point of the system is to simply make it as quick, easy and rewarding as possible to create or edit online content.
