I'm running hot and cold with Google+. It's got its uses, and its main draw is that it's not Facebook. I still am sort of thinking it's going to turn IN to Facebook, and Facebook already has all the integration and handiness (like APPS THAT WORK---haven't I mentioned this previously?). Something I have just begun to consider is the total lack of anonymity with Google+. Facebook makes you use your real name, more or less, but with Google+ you have to tie your e-mail account to your social media activity. That's really pushing things to the next level. I have a Google+ icon on my blog sidebar because the blog is already associated with my name through print media and other means, so there's no point in trying to keep it hidden, but not everyone is like that. Unlike Zuckerberg, I'm not into radical transparency, and neither are a lot of other people.
This is not a deal-breaker, but it's something to consider. At least Facebook allows you to block people a little better and hide your e-mail address. There are pros and cons to everything, I guess.
