Awesome news! Hamilton Verissimo is joining Microsoft. These are just great news because another great open source developer is joining the Redmon company. The CastleProject should be mature enough to survive without Hammett although he says he can still work on it. Best luck mate, congratulations.
I hope Microsoft develop more open source projects like IronPython and the super hackers they are hiring leverage the company with the open source spirit.
By the way, regards to my colleagues Atilla and Ben who joined MS last year in Dublin 🙂
