When the head of Google + stepped down recently, the assumption was that Google seemed to be backing away from the original Google+ strategy, in which it tries to compete with Facebook and Twitter.
It makes sense for the company to back off of forced integration of Google +. As a Google user, I'm happy to use the tools I select - I don't like the fact that I must create a Google + profile to upload content to You Tube, for example. It adds a layer of unnecessary complexity to something that should be relatively straightforward (a standard Google profile).
In short, if you must force your users into your Social vision, you're doing it wrong. Do you use Google +? Why or why not?
