I didn't quit the Rails Core team (http://rubyonrails.org/core). I no longer work full-time on Rails, but I've been continuing to work with other members of the Rails core team on maintaining code I wrote (most notably encoding-related code and code related to the Railtie system).
I've also been contributing more code recently, and after taking something of a hiatus, have gotten back into it a bit.

No drama here!
