What is a wiki?

A wiki is a website that allows its visitors to write content collaboratively.

The users of the site can edit the content, making changes to what has previously been written by other readers.

There can be several pages of content connected by hyperlinks. As the content is editable there is a history of changes to enable users to revert back to earlier versions.

The most famous example of a wiki is Wikipedia, an online encyclopaedia written by its readers. The English version, which can be found at http://en.wikipedia.org, has nearly two billion articles. The Cantonese version is located at http://zh.wikipedia.org.
