I played around with this for a bit, it seems okay. It seems to me like a potentially better way to do it would be more so in a Khan Academy style of doing things, where there's a video that you follow along with, and maybe have your text editor in a separate window so that people can work on the code while watching the video, and then exercises that you do after the tutorial video that people can comment on and get help with from other users and the creator potentially. I personally think net.tutsplus.com does a pretty good job at this, but I think your site could do it better if it offered a more personal experience.
