We're building an education product (http://whatispolymath.com) to help users learn programming & design from the best resources around the web in a fun and engaging manner.
Our private beta just went live and we're looking for early users to join & engage in our community and give us some honest feedback. We're trying to cultivate and grow this in a controlled manner (think early days of Quora) and would love for some smart, motivated hackers/designers who are interested in education to join. Perks include pleasant UI, conversation with similarly motivated folks, and the chance to share your knowledge with the world :)
