Do you know what is a Wiki?

When we try to write a paper and find sources our professors tell us " Don't use wikis as your resources! We will not accept them." And I wonder why???
A wiki is a Web page that can be viewed and modified by anybody with a Web browser and access to the Internet. This means that any visitor to the wiki can change its content if they desire. While the potential for mischief exists, wikis can be surprisingly robust, open-ended, collaborative group sites.
Wikis permit asynchronous communication and group collaboration across the Internet. Variously described as a composition system, a discussion medium, a repository, a mail system, and a tool for collaboration, wikis provide users with both author and editor privileges; the overall organization of contributions can be edited as well as the content itself. Wikis are able to incorporate sounds, movies, and pictures; they may prove to be a simple tool to create multimedia presentations and simple digital stories.
The information about the wikis can be found in http://www.educause.edu/ir/library/pdf/ELI7004.pdf
According to these data wikis can provide students with useful information about a research topic, but on the same time the reliability of the sources are under consideration.
