Eldarion flipped the switch and open sourced Kel yesterday.
While I was heavily involved in the launch, it was more from a project management, process, and promotion point of view. The technical work is all down to @brosner.
While I've been using Kel internally as an end-user (i.e. deploying sites), I haven't had a chance to really dive into the code itself yet so I'm basically a n00b. I plan to record my adventures here.
