Hey, brother! Long time, no see! How are you doing, man? And about Google+? Yes, it still need a lot work. Good to hear from you and hopefully to chat with you. Take care and catch you next time. Oh, I almost forgot, I'm divorced!!!
My circles are growing little by little with good and not so good people. For those that you are not really into them, you just put them on a "I don't care circle" and ignore them completely. That way you don't feel compromised to talk to them, at the same time they don't feel rejected.
