I hope this isn't too off-topic, but since this is the perfect mix of hackers + people interested in education... Quizlet.com is the startup I'm working on and we're also hiring. We're a for-profit but strongly educationally focused web company trying to help improve the way people study online. Different than (complementary to) Khan Academy, but gaining traction with 1M+ registered users. Get in touch if your interested.
