I Like Google+ a lot as well. Facebook is where my clueless family, neighbors, and random work associates find out what each other did last weekend. its gossip and bullshit. "Who is dating who" or what relative has the cutest cat pictures.
On google plus I have meaningful discussions on the latest tech developments, can get into depth on why I like a particular artist or musician, ask a question and get answers from actual experts in their field, and have circles devoted to just role playing games, or 3d printers, or contact juggling, or mesh networking routers, or auquaponics gardening, or food forests. I'll post my health issues on facebook, but if I want to talk about the latest Hans Rosling Peak Child video, its not going to be with my cousins.
The closest I come to that sort of thing is Reddit. not facebook, and reddit is LOUSY for one on one conversations and following particular people.
Google+ is absolutely my favorite platform. I love it. I use it every day, I have fifteen thousand followers, and I launched a collection of short stories due to help and support from people I met on there. I have the maximum number of people I'm allowed to follow, and the content of my stream changes every few seconds. There ARE things I don't like about it. just like there are things I hate about slashdot, reddit, and facebook. but I almost completely stopped using slashdot, and replaced it with streams on g+
