Online gaming syndrome

I wanted to share an interesting post by Edward Castronova on Terranova on "Online gaming syndrome." It reports on a Korean doctor who links online gaming with deep-vein thrombosis. The comments following the post are interesting too, because they include input from MDs on the validity of the research. I posted my thoughts in the comments as an addendum to what was presented as well. Check it out.
