The Sputnik Observatory is filled with videos similar to TED, in a very innovative interface: http://www.sptnk.org http://www.sptnk.org The videos are shorter, but the site tries to link you to similarly interesting conversations, and hopefully expose you to something you weren't aware of. It's also growing rapidly, and will have a lot more video up in the next couple of months!
