Wiki's in the classroom!

I enjoy wiki's. I understand that some people have a grudge against wiki's like Wikipedia, as anyone can change anything on the site. However, I believe that, for the most part, they are fairly reliable sources of information. In the classroom, I believe they are an excellent way for any group to make a site, whether the sight were some easy way to contact one another or as the project itself. Wiki's have been and will be a major source for open information sharing, and I believe that our students need to be knowledgeable in this area.
