The Internet. A great tool for people to share their feelings about businesses. On Google.
Facebook is social. Google+ is business. Right now, that means far more money for Google. Say what you will about them, Google does not leave their monopoly profits to whither on the vine. They use them to crush upstarts, innovation and competitors. For the benefit of users.
It's just that, for Google+, the users are businesses and the new platform is for their beneift.
Not that there's anything wrong with that. It's just that despite all their examples, I'm not terribly interested in interacting -- on a social level -- with the various businesses I transact with. No matter how hipster cool and, you know, personal they tell me they are. And no matter how much they believe they have a mission "to inspire" when really their mission is to sell flour.
