Looks interesting if niche. Somebody should take all the documentation and create gamification experience around it. With levels and all. Maybe even as a submission to the currently running Gamification Coursera class....

I can just imagine: Level one: you managed to download all sources. All the way to "You are the master, you can now serve your own ??? (ruby on rails app?) from your own server".

Then build a community with badges and pledges and things around it. Have a side quest or two for the adventurous players.
