I guess it seems like a silly rule because it's unenforceable. Unless your checking passports or something, how would one know it's a real name? However I am glad to see that they at least look like real names. It weeds out things like "hip young dude" or "movie fanatic" as user names. Only thing worse than bad usernames are those annoying, flashing little gifs. Anything that maintains an intelligent dialogue and keeps the sullen teens from just hanging out, I'm all for.
