Aside from two John Smiths, there's also the problem with celebs. William Shatner had his G+ account shut down on suspicion that someone was registering it as a "fake name". So it appears celebs may have to go through considerable hassle and scrutiny to get a G+ account (not to mention the hassle of exposure). Bad news.
