I don't want to use Google+ because everyone I care about uses Facebook, and even that I'm growing tired of and use less than I did for a few years. I'll continue to use my Google (Gmail) account for authentication to StackExchange and a few other sites, because it doesn't make me use anything but Gmail. But, if Google starts forcing me to use Google+ actively, I'm going to stop using it for authentication.
