Google+, Facebook, twitter

It's been a while...what's going on with Google+? I think we can conclude it isn't a Facebook killer in anything like the medium term. After moving away from Facebook I started posting again because almost all of my friends in "flesh space" simply don't use Google+. Rather, Google+ has become a more elaborate extension of my twitter circle. I've got over 2,100 who've added me to their Google+ circles, and only 1,600 twitter followers. But I don't do post much on Google+ at this point. For someone with my amount of time and interest two social networks seems optimal in terms of complements. That being said, as many have noted Google+ is more than just a social networking platform. Rather, it has to be understood as an extension of giving your whole suite of Google services an identity, specificity, and personality. With all that said, Facebook is starting to get a little too busy for my taste. Does anyone else feel the same way? Mark Zuckerberg has known how much to "push it" for years, but my own suspicion is that he has to be very careful of a rapid implosion of usage due to feedback loops if he moves beyond a particular threshold.
