I deactivated Buzz. It seems Google's so desperate to enter the social advertising market that they're inconveniencing their users so much, so I refuse to use Buzz for this simple reason. Google doesn't know what's best for me. I do. They need to stop forcing me to use things I don't want. If I want to use them, I'll turn them on, or request them.
I'm content with facebook, that by the time I'd heard about Buzz I'd already heard about problems (like this one) that would drive me away from using it. So, currently at least, I've decided to avoid Buzz. If I never experience Buzz during its existence, so be it. I use Docs, Analytics, Gmail and Reader, I'm a rather loyal Google user and Buzz just seems to be aimed at screwing all that up.
