No, Facebook hasn't just constructed a real, physical space for people to exercise and play sports. Deity forbid they do something that will actually unhook you from the social network. Instead, they have created the virtual equivalent of a sports forum where both fans as well as rivals can dish it out with words, something people already do on Facebook anyway. But now you can do it officially and with game stats right in front of you. In short, Facebook has just created the social network equivalent of a sports channel.
