youtube

YouTube? A place to watch funny movies created by Your friends. (Yeah, it's a king of entertaiment...) Sorry, but definitly not.
A great source of incredible valuable movies. Academic lectures, classical music and so on.
Sometimes I think that YouTube is better than RMF Classic :P
And lectures or other ideas spreading the world in several days. That's one of these things the Internet was invented for.
I promise to put some links to worthy stuff from time to time.
