An early adopter by nature, Cristos first discovered computers at the age of 3 (on his parents' Mac Plus, before he could read). Since then, he's often been an active lurker in online locale-based communities, such as the b0st0n LJ.
This course, with its emphasis on communities in cyberspace (see Snow Crash , by Neal Stephenson), particularly appeals in that way. (The fact that Second Life looks like a video game doesn't hurt any, either.)
When he's not talking about himself in the third person, Cristos spends his time at a Cambridge-based company working on their website redesign. If he had any free time, Harvard Aikikai would probably take up the rest.
