This is great news. After watching Salman Khan's speech at TED I got really excited about what he's trying to do for education. I really wish more public schools would shift their focus from in-class lectures to working with students in a more personal way. I certainly hope the site gets more contributors from other disciplines, the majority of their content is still mathematics. Anyhow... I'm excited to see where they take this in the future.
