Google+ was a copy of Facebook, in that it didn't introduce really different new concepts or differentiators. I know, "What about circles?" Well, one big thing that people demand was privacy. That's why people built Diaspora & co and Snapchat. Google got Circles right, but one can't trust a social media which also owns your emails and Youtube comments, and they indeed screwed us with the Real Name Policy and the intrusion of G+ in all things Google.
