I enrolled today.

I wonder what the intentions of these universities are by offering these courses for free. (seriously) hm...

It might just be me being a pessimist, but they have to have some kind of evil motive, right? It seems unheard of that any university offers something for free.

Found this article about Coursera... http://www.reuters.com/article/2012/04/18/net-us-usa-college...

I guess I'll just enjoy it while it lasts.

For the OP I'd suggest why's guide http://mislav.uniqpath.com/poignant-guide/book/chapter-1.htm...
