Wiki is web server software that allows users to contribute content. Collaboration is the key to Wiki, which is designed as a powerful system for online communities to build web pages and web sites. Unlike blogs and forums, all users are allowed to contribute and edit existing content. Wiki is derived from the Hawaiian term "wiki wiki" meaning "quick". The concept behind a Wiki is that collaboration on projects will move it along quicker.
Wikis generally allow web pages to be written, edited and created collectively in a web browser. Wiki supports hyperlinks and simple text. Most Wikis are open, and allow any user the ability to edit the contents of a Wiki web page. While some say this opens the concept to abuse, Wiki moderators and self-policing in the Wiki sector appear to be taking hold. Wiki supporters generally feel that it is generally easier to correct mistakes than create the content from scratch. Wikipedia is a standing symbol of what many would consider a succesful Wiki.
