The main project I work on is my day job: Kiln, a cutting-edge DVCS hosting solution based on Mercurial that integrates tightly with FogBugz. I also continue to work on Fog Creek Copilot from time to time. You can track other projects I'm working on by visiting my Bitbucket account, where you can find, among other things, most of the code that powers this site. I also keep mirrors of the more useful stuff I do at GitHub. Patches and feature requests are always welcome.
