If I do so the Apps-admin will have full control over my account including reading my private messages, deleting my account... right? Besides trust issues I wonder what would happen if I leave the company? How do you handle this at Google?

What's your experience at Google? Do all off you habe 2 accounts and if so, don't you have problems making sure that your not work related friends etc. don connect with the wrong profile?

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.

Otherwise the risk for accidental spillover just seems too high...

Is this a per company default setting? Can company admins set the defaults for all company users? Or is it an individual user setting?

Now if you do a corporate G+ post and say "Bob in accounting sucks" and then share that with Bob--that's on you. :)

I don't know why, but psychologically I would feel like this is somehow less private than, say, a mailing list. I'm probably becoming old :)

I think that's a really interesting comment! Perhaps it's because the UX is more social network-y (FB/Twitter), which are historically public, and less email-y+historically private?
