Opted in to Google+ recently, and for a few days was sent into a loop of "X Added you to Google" --> "X Added you back to Google"--> "Add X to Google?" --> "X Added you to Google".....
But once that frenzy died down - I can see how it could be useful at work. We held one of our last team meetings via a "Hangout" and found it fairly easy to set up and use. Could be good for chatting with out-of-town family (and for providing long distance tech support).
