Title: This caught me by surprise, so I thought I'd share it. You can go back to your google profile settings and uncheck "Display my full name so I can be found in search" and "Display the list of people I'm following and people following me."
I think the privacy settings are all around lacking, but this "feature" was pretty opaque to me--they gave me an option to "save" my google profile when enabling buzz, but since I already had one set up I thought this to be an irrelevant step. I had to poke around for a while to realize that my profile had been changed.
