I'm guessing most haven't heard of Ted.com

That's the place to go if you want to learn from Big Thinkers around the world, in any category, It's been around for quite some time now.

I like the site. I just watched a few interviews and they were all above average. I'll definitely come back. But I have no idea how it will scale if they have to conduct every interview.

thats a good point, but I doubt they are planning to do all the interviews themselves, I think the article mentions that they just want to add any related video in there, i.e. interviews, lectures and anything else of that sort ... but if they don't there is no way it can scale, it will be like a tv show with a couple of episodes a week

Very cool idea, but I wonder how profitable it is, especially if they intend to continue producing all their own content.
