I got frustrated while trying to study Artificial Intelligence, so I created this site http://knospot.com/ , you can know about it here http://knospot.com/hello/about . Many of my friends say its a good idea. Having a full time job make it difficult for me to maintain it, plus having a partner to program will motivate me more and help me to think add features.
If you are good in Rails, have time, want to make the world learn better and efficient, then please reply me. Would be more than happy to hear from you.
