Google's Identity System

I haven't been able to get into Google+. It looks pretty and I know it gets some users very excited, but I already have a presence on Facebook (a service I don't love) and nobody I know is using Google+.

Is it possible Google isn't actually competing with Facebook? That's a theory put forth by Ben Thompson, once again on his stratēchery blog today in response to a piece by Harry McCracken.

I need to give this some more thought.
