Probably. It linked up an old Blogger account of mine that I haven't used in years. It could have been embarrassing since it was exposed to all my GMail contacts who might have enabled Buzz including people I barely know, work collages, etc. The Blogger account has a bunch of stupid stuff on it that was only intended to be viewed by friends. I'm quite sure someone could have found it by cyber stalking me but to have it shoved in their faces is entirely different. Of course I'm not even sure what other people on Buzz could see. There's no clear distinction between public & private information.
