Facebook is the backbone social network. While other platforms will come and go, unless they screw it up, Facebook will, for a long time, be the Alamo of social networks; the fallback, the final rallying point, the basis from which the branches of knowing 'who's who' extend.<p>As long as they understand this and don't jeopardize the position Facebook should be around in this minimum capacity for a long time to come. In the short term I think they are doing the best they can do to position themselves for newer and longer technologies.<p>I wish them all the best and hope to see some real, concrete innovation from them in the next few years.
