answer:Google Plus is not insisting on real, legal names. They are instating the same rule that Facebook has: That it be a name you are known by in real life. Samuel Clemons, were he alive, could go by Mark Twain. 50 Cent is allowed to go by just that. You aren’t allowed to go by anonymousdude887. However, unless you are famous, this is a largely unenforceable rule – my name isn’t Amy Smith, but how would Google know that, and how would they even begin to know that it’s not a fake name I use in real life (perhaps when trying to pick someone up for a one-night stand)? And you definitely don’t have to go by a legal name – I go by a nickname, not my legal name in daily life, and Google’s not trying to take that away from me. I think we should be concerned, but I don’t know what we should be more concerned than with Facebook or other internet giants. I don’t want to get mad at Google for mining data, but not get mad that all public Tweets are stored forever by the Library of Congress. Or not be concerned at all the info various apps on smartphones get.
