The only thing stopping me from linking my channel to my G+ account is them changing my username to my real name. I've built an online brand around that username and changing it would mean i'm harder to find on Youtube. (funny enough that name is different from my HN name, since I can't change my HN username and don't want to lose my Karma.)
