I'm a pretty big fan of wikis (not sure of the plural form) and of Wikipedia. I find myself using Wikipedia all the time now - just recently researching EV-DO wireless technology.

At the same time, working in an educational environment, I also hear a good deal of discussion regarding the reliability of information found in Wikipedia.

In this article, Andy Carvin takes a unique approach to introduce Wikipedia to his students and in my opinion, helps sustain and support it.
