Agree with you. Facebook is an old-time player in Social Media business, so when G+ comes, most of people already get "stucked" with FB.
This is a completely different project that almost no one uses because of the inconvenience and the presence of more attractive social networks.
Google+ never made the cut, ever. The only time you needed to know what it was and how to use it is if you were going to actually apply to a job AT google.
