Show HN: A crowdsourced teaching platform. May the best teachers win.

I'm a long time lurker on HN, and among other projects, about two years ago I began creating a textbook replacement.

In short, it's a free, crowdsourced, and dynamic online textbook that rewards quality instruction. It's ideally a platform anyone can learn or teach from in every subject, and I hope it will harness the Salman Khan's of the world.

Reddit gave me some great feedback over a year ago, but I've been so busy with my normal life and day-job that it has fallen to the wayside. It's still rough around the edges, but I wanted HN's opinion of the concept before I put more effort towards it.

Any input would be great.
