What is: Wiki?

IDG News Service - Much of the rising interest in wikis stems in part from the success of Wikipedia, a free online encyclopedia that relies on contributors to add and edit entries. Since its establishment in 2001, the English-language version has grown to include more than 480,000 entries and has generated versions in a host of other languages.

Wikipedia may be the best-known wiki, but it wasn't the first. The world's first wiki, a computer programming site called the Portland Pattern Repository, was established by Ward Cunningham in 1995.

How is a wiki different from a blog?

A wiki possesses an "edit this page" link that allows a visitor to make changes to the page. This link is what makes wikis different from Web logs, or blogs, which permit readers to give feedback on a particular comment but prevent them from editing anything but their own postings.

Wikis also require only an Internet connection and a Web browser for access, which can make them easier to deploy and use than some collaborative applications or groupware offerings. Having people share information on the wiki can also ease overloaded in-boxes and cut down on e-mail exchanges between co-workers.

Why should marketers care about wikis?

For companies that have trouble keeping up-to-date information on a corporate intranet, wikis can enable employees and customers to make changes themselves. They can also help coordinate internal development projects -- an area in which they have already started to make corporate inroads.

Wikis can also be used to build online customer communities that offer advice and support. Some companies may balk at the idea of opening up a site such as this to the public, but the trust extended will likely be repaid with increased customer loyalty and satisfaction.

Who controls the content of a wiki?

In theory, no one and everyone. Every reader has control over a wiki's content and can make changes, additions or deletions as they see fit. This lack
