Jeff Ma is one of the smartest guys in online sports (and personally a great guy, too). I thought ProTrade was really cool, but when it didn't get the traction it was expected to, Ma pivoted the company as Citizen Sports -- focusing on the intersection of sports and social media. Sure, I could declare myself a fan of my favorite team via Facebook (one of their offerings), but the real potential is in interactive apps...like fantasy sports. Ma partnered up with SI.com (which desperately needed a fantasy footprint -- and the cachet of Facebook is a strategically valuable bonus). Good pick-up in USA Today about it. Definitely tracking... -- D.S.
UPDATE: Interesting celebrity-league opportunity here for one fan, too.
