Gorilla made an excellent argument on this issue, so I can't really add much.

I will say that in my experience teachers are consistently on the wrong side of technology, particularly the web, and it's use. why would a teacher encourage their students to use Wiki, it would make them less of a reliable source?

While teachers blast the open source methodology of Wiki, they fail to suggest a better alternative. Print media and proprietary college databases of information are by no means a viable alternative to the sheer information power of Wiki.
