Silicon Alley casualties may like to work out some of their frustration by taking this martial arts class. Jason Calacanis was editor of the Silicon Alley Reporter, the defunct journal of the defunct New York internet scene. Aside from a bit part in Wayne Wang's last movie and a fondness for Bikram Yoga, Calacanis also teaches Tae Kwon Do on Mondays at 19.30. Email him if, after the internet bust, you want another beating.
