Integrating with version control systems, such as git, is quite high on my list of things to do (but it's a big list). My next move is to try and get other users to add their content onto the website, and github seems like an excellent place to start.

Also, you mention about proving that it is an efficient way to learn. That's a good point. Rather than assuming that people will like the format I should try to prove that it works, maybe by providing a comparison with some existing documentation.

Thanks wanghq.
