“Google’s social network only accounts for 2% of all social sharing across the web.(…) LinkedIn is actually beating Google+ for shared content with a 3% share.”
It’s pretty shameful to see how much Google has been investing on Google+ and how little the return has been.
Google+ is sort of their Ping. Except Apple had the good sense of shutting Ping down when they realized it wasn’t gonna go anywhere, and Google keeps shutting other services down to try to shove Google+ down everybody’s throats.
