New Wiki - Education

I always think up stuff and shortly there after other people come to the same conclusions but implement them. With the take off of Wikipedia I think the time has come for an educational wiki to take off. It would probably focus on the sciences and mathimatics as they are less controversial. A wiki is a completely different animal than a standard text book being that it's multi authored and it's one huge hypertext document spanning all topics in a field of study. Instead of a textbook on chemestry it would be more like an encyclopedia of chemistry but far more readable. It's a great way to learn a topic as it's non linear.
