The name policy opens with:
Google+ makes connecting with people on the web more like connecting with people in the real world. Because of this, it’s important to use your common name so that the people you want to connect with can find you. Your common name is the name your friends, family or co-workers usually call you. For example, if your legal name is Charles Jones Jr. but you normally use Chuck Jones or Junior Jones, any of these would be acceptable.
I found it very interesting when I signed up that Google+ recognized my maiden name. Especially since I've been a Mireau since 1993. It was a great reminder to review my privacy settings.
Google+ is optional. No one says you have to join in.
