Mark Zuckerberg likes to say he just wants to make the world more connected. Right. And both Bush and Obama were going to "unite" us, not divide us. Zuck wants us to be able to share anything and everything, all of the time, no matter where we are or what platform we're using. He leaves out one important point: Facebook is built around the premise that we'll be able to put up with each other's crap, when we really don't have to, for eternity.
