I'm not so sure about that. Have you visited the link from shabbir's post? My understanding from it is that to begin with clicking on the G-plus is limited to those who have a Google profile, and then they can only share it with friends who also have a profile.
My friends all know what I do anyway, and I'd be surprised if many of them have a Google profile, they are all already on Facebook. I realise that Google obviously wants more and more people to sign up so that it becomes more useful, but I am wondering whether social networking has already peaked.
