And hence we see the strong movement at Google to roll their own, Google+, and make it successful. They need to get the flavor and the detail of the real social networks that move buzz and communication.
I donīt know where are you located but we in germany do NOT use google+.
Google have discounted the authority sent by poor links due to the fact that they may have been brought / paid for, will this transfer to the authority gained via social media?
Here's another one. Have you ever watched account after account start following you on Twitter and then all of a sudden all those accounts are deleted in one swoop? Twitter is not sleeping on the job, either.
