The point of Google+ seems to be to do networking with your friends and co-workers. Why would one want to be anonymous in this environment? You're going to anonymously share pictures of yourself? I do not get it. If it's a pseudonym that you just happen to really like, then okay -- maybe you've kept it since your days on AIM and are really fond of it, after all things like JHR1987ILOVETHEBEATLES are pretty cool -- but other than that what is the point of this?
It seems like wanting the right to carry a gun in space. It's not going to do you any good, so why are you fighting about it?
