MyToons

Still buggy, MyToons came out of beta today. What's MyToons? Basicly a website in the likes of YouTube, but only with non-x-rated animations. From their website:

MyToons.com is the world's greatest online animation community. It's the place where people who really love animation - from seasoned industry pros to rabid animation fans - can upload and share their creations and animated favorites with the entire world for free. There are so many exciting things to do and see it's hard not to have fun.

Technicly it could be way better, but it has the advantage that, at least for now, the garbage ratio is low. If you have some time to spend and like animations, this website might soon be your homepage.
