Sports are inherently social – a topic that has always brought people around the water cooler.  It’s not a stretch to say sports are one of the most “social” topics. Almost everyone has some team, player or sport they support.  And you share these bragging rights with friends/family/strangers/co-workers at bars, around the TV, on sports-talk radio, over the phone, at work, essentially everywhere. And now, increasingly across the social media world.  Sports talk thrives across blogs, Facebook, MySpace, Twitter, websites –it’s ubiquitous.
