A wiki is a website that allows pages to be added, deleted or edited by multiple users, including the general public.http://www.oreillynet.com/pub/a/network/2006/07/07/what-is-a-wiki.html Wikis can serve a variety of purposes. They allow a potentially unlimited number of people to create and edit a single document as they collaborate and share information. Wikipedia, one of the world's most visited websites, even used a wiki format to create a user-editable encyclopedia.http://en.wikipedia.org/wiki/Main_Page

An iPad wiki allows iPad users and owners to collaborate and share information about the iPad and the iPad's third party applications. iPad wikis can change and grow over time to include more and more in depth information about any individual aspect of iPad use.

iPad wikis can be used to gather a variety of different types of information about the iPad. There are also many different iPad wikis online. Some of the more popular iPad wikis include iPad.org and iPad-Wiki.com.http://ipad.org/wiki/Main_Page http://ipad-wiki.com/ Many popular iPad wikis are designed to contain as much in depth iPad information as possible. They may offer information on supported audio formats, Windows system requirements, iPad technical specifications, supported video formats and other information that can be hard to locate elsewhere.http://ipad.org/wiki/Main_Page

While iPad wikis can be an effective way for multiple users to share their iPad knowledge, wikis also have a tendency to be messier and less organized than sites that are curated by one person only. They also need frequent monitoring to remain free of spam.http://www.oreillynet.com/pub/a/network/2006/07/07/what-is-a-wiki.html?page=2#disadvantages
