(nods) I see what you mean. I do wish there was maybe a little more granularity to Google+ (though it's leaps and bounds better than Facebook), or at least, a few less things exposed by default. I was a little disturbed when I updated my profile picture on Google+, and it suddenly appears in all my emails, my chats, my contact lists, other people's contact lists, their phones, their emails, etc.

I mitigate the risk a little by conducting super-important business stuff through either my @idkfa.com or @intersectionthereof.com email addresses, and having them simply backed up to Gmail in case of failure.
