A wiki is a collection of web pages designed to enable anyone who accesses it to contribute or modify content, using a simplified markup language. Wikis are often used to create collaborative websites and to power community websites. Wikis are popular collaboration tools because they allow registered or unregistered users to add, edit or delete content without knowing HTML or other web-based computer languages, track changes made by users and revisit different versions of wiki pages.
Future Melbourne, City of Melbourne, Australia , Planning Wiki at http://www.futuremelbourne.com.au/wiki/view/FMPlan
The City of Melbourne is using a wiki for public consultation when researching and drafting a new strategic plan. During May and June, six and a half million people visited the site. The wiki enables wide-scale collaboration unrestricted by time or geographic constraints. This meant that a wide variety of participants could take part whether city residents, city workers, visitors or students. Since the participation is online, participation could occur on a 24 hour, 7 days a week basis.
Crisis Commons Wiki at http://crisiscommons.org/wiki
