I have one because a lot of tech people are on there and it's easy to get news I don't wanna subscribe to. But given that Google won't allow me to use my actual internet identity of ten years, I've merely got the account set up as a first name and an indistinguishable initial. Google have done a fantastic job in alienating me as a user. What's hilarious is that the name I want to use and wouldn't mind associating with my G+ reviews is the same name that I use on my email account. Google apparently doesn't care though, so no reviews from me either.
