Improvements to education (expand the Khan Academy model beyond mathematics) - Khan Academy already has a great model with the videos and exercises for mathematics (go contribute at https://sites.google.com/a/khanacademy.org/forge/for-developers/getting-started-with-the-code https://sites.google.com/a/khanacademy.org/forge/for-develop...). The exercises don't extend past maths, and i think would need some conceptual tweaking to apply to e.g. languages or programming. I'd love to get something up for this - anyone want to join up and brainstorm/rapid prototype a project? Reply to this thread or find me on Google+ and let's hangout. Thanks wz3chen!
