I opted in Google+ long ago, I can't remember the reason, probably none, although I expected that the change would be compulsory after a period, like it's now revealed. I just don't post stuff intentionally on it (don't use it as a social network), and I don't have any picture or personal information or even my complete name on it, and I already configured everything--yes by default it's like Facebook more or less, plus they also have your email, search history, etc.

I do have a couple of reviews of places on the map, because it helps other people, the same way that I also need them when I go to an unknown place. The difference is that previously it was possible to write reviews anonymously ("a Google user") and now you must log in. But this change happened much earlier than the YouTube one.
