A video was just put up of Salman Khan at TED this year. If you haven't heard of the Kahn Academy yet, watch the video and then check out the site. In short, the Kahn Academy is "on a mission to deliver a world-class education to anyone anywhere".
Salman Khan does a great job teaching, and what him and his team are doing for education is just amazing. Really, I think this guy should be running everything.
