Retarded move. I have a public profile but no longer wanted Buzz. I had to re-create my profile after getting rid of Buzz.

Someone screwed up in the backend. They'll figure it out because that is bad (or a deterrent ;-) ).

Unless this is recent, the bottom of the gmail page there is a button to 'turn off buzz' just like you can for chat.

I don't recall it notifying me of any changes to my profile.
