A wiki is an application that allows Web users to contribute to a site and edit its content. Collaborative Web sites based on the wiki principle are themselves known as wikis, a term derived from the Hawaiian word for �quick.� The most famous wiki is Wikipedia, the comprehensive online encyclopedia whose underlying philosophy is that a community of users will correct errors even though contributions aren't subject to the verification found in traditional publishing. But the wiki concept is also used for other public sites and for corporate intranets -- often moderated by editors.
