Here’s what I’m working on now – in no particular order:

Sayspring: CTO

Steve Yegge’s Ten Challenges: Starting from the top, finished Gödel, Escher, Bach. Starting Structure and Interpretation of Computer Programs shortly.

Lunchhall: A web app that helps you follow specific people across multiple channels (Blog, Twitter, other publications)

Play It Out: A mobile chess app that helps you get better at chess endgames in a bite sized way. About 80% done, currently putting the finishing touches on the other 80%.

Lets Grab Lunch: A mobile app to help you keep in touch with friends and colleagues by allowing you to set long term reminders to reach out and grab lunch or coffee.
