I have been using Google+ off and on since the release and I struggle to find a mainstream use for it. It seems to me that Google+ is really a social networking site for Google employees, Google products and services, and other Google related news for Google employees, and fanboys alike. If there exist a Non-Google related page, it is probably more active on Facebook and receives more updates. In a nutshell, Facebook can replace Google+ but Google+ can't replace Facebook. Regardless, Google pushes on and I can understand why.
