Topic: Twitter clone tutorial
I'm writing a series of articles on building a Twitter clone, including tagging, mentions, and a realtime web interface. I'm trying to set the difficulty at a level that anyone discovering Rails for the first time could deal with. If anyone has any feedback on them, or requests for things to cover, then I'd be delighted to hear. The first few parts are online now, with more coming daily.
Otherwise, the tutorials are all at My website - jgwmaxwell.com, I hope they are of use to someone.
