PSA: I don't really use Google+ at this point, I'm too pissed about #nymwars. http://twitter.com/#!/search/%23nymwars I haven't deleted my account, but I don't keep much of an eye on it. I'm mostly active on Twitter and somewhat active on Facebook.
I didn't read the whole thing, but I definitely agree that forcing exactly a first and last name is very broken and displays a surprising lack of internationalization awareness. I'll refrain from commenting on the real names policy, given that I work at Google.
