This is something that's puzzled me. Is it the privacy implications, or just a general dislike for the company? The way I see it, it's a publishing platform for posts shorter than blog entries and longer than tweets. I read things that my friends write, and I write things for them to read. While there are games and pages and things, you don't have to use them.
I've had friends switch (switch, not start to use both) from Facebook to Google+, and treat it in exactly the same way as they treated Facebook. So I'm not sure if Google+ is better by its own merit, or just that Facebook has a bad reputation.
