I've seen plenty of people on HN tout Khan Academy as the awaited usurpation of the education system. Many also call it "the future of education" in a vein that it's meant to replace parts of the educational system. I think Khan Academy is going to do wonders for the American K-12, if teachers are made aware of its advantages.
