Any employee who uses Gmail personally has two accounts, yes (I actually have four - personal, .edu, my pre-Google startup, and Google). No one outside the corp environment can see my corp account. From my corp account, I can't find my personal account by searching. If I go directly to my personal profile page and try to circle my personal account from my corp account, I get an error "due to domain restriction".

So I guess the short version is no, what you are concerned about won't happen.

It won't happen for Googlers, but it will happen for G+ business users, since they (afaik) can't make their profile fully private, and it won't be entirely silo'ed.

Is that true?

Thanks for clarifying.

I have a corp account and a personal account. What I do is make two different pictures for my avatar: I use one avatar of me for my Google-internal account, and a different avatar for external use. Then I can just look up and see which picture of me it is, and I instantly know whether I'm on corp vs. personal.

what about rel="author" and authorrank?

I believe it's all linked to my personal account.
