Thank you so much for this. I, too, don't have a lot of emotion connected to my "real" name--and in fact, frequently people say the phrase "the name you were given at birth" which, since I was adopted, isn't the same as my "real" or "legal" name. (Never mind people who have their names changed for a myriad of other reasons.) So many of us have well-used, ingrained nicknames that actually do differentiate us much more than our real names. It's just an odd and silly policy, not well enforced.

And frankly, at least FB was really clear from the start about what they wanted me to use for a name, even if they don't enforce it consistently and even if I don't agree with them. G+ absolutely was not.
