Sure there is: it's Not Facebook. That means a lot, really: No Aunt Martha seeing those pics from Atlantic City that you might otherwise like to post for your real friends to see. No friend requests from that asshole in high school that used to beat you up and now wants to pretend that everything's copacetic. No Farmville spam. No six-times-a-day status updates from that one person in your circle that just loves to "hear" themselves "speak" No profit for Zuck. You get the picture: there are a lot of reasons that people have left Facebook lately. It no longer has the exclusivity that drew the early adopters originally, and as we're getting older and realizing more and more that we want some privacy, Facebook has resisted making it easy to come by. Even better, beyond just being pre-Eternal September (and let's face it, once Aunt Martha is on Facebook, it's that time...), G+ has mechanisms in place that seem likely to keep the S/N ratio that I see high for a good long while. Sure, plenty of people don't care, and they'll keep using Facebook, and that's fine. But right now, the most important thing that differentiates G+ to me is that the people I care about interacting with are actually using it, even though many of them haven't been active on Facebook for months, if not years.
