Both of Google's posts on the issue talk about notification and controls for users whose profile is created when they first use Buzz. But from my experiments, if you were in the minority of users who had already set up a Google profile (which I did in 2007 when they were first announced[1]) then Google started broadcasting information about who you were following before you even knew that you were following them. Adding new privacy controls is not nearly sufficient to protect privacy; you need to notify users about them and let them choose before applying the settings to their account. At least during the first launch (I haven't re-tested with the latest changes), for my test account that already had a profile, this was the experience: (1) As soon as I logged into GMail and saw the Buzz welcome screen and clicked "no thanks," my account began "following" people chosen by Google. (2) This information was broadcast to a group of people chosen by Google. (3) I was not informed that either of these things had happened. (4) New privacy settings were added to my "Edit Profile" screen, but (5) the least-private setting was activated automatically and I was not told yet that the new settings existed until after information about my email contacts was broadcast to other users. I don't think anyone disagrees that there were privacy controls. But it was really a "beware of leopard" situation, at least for accounts in this particular state. The only option for these users to preserve their privacy was for them to (1) magically know that before logging into GMail today, they must edit their profile to be non-public, and (2) magically know that new privacy settings had been activated in their account so they could change them before trying Buzz. Now, I actually like Buzz and am still using it[2]. I think it's a much-needed challenge to Facebook's closed platform. I can see how the Buzz team didn't forsee just how bad this would be for a very small minority of users. But to pretend that all users were given a chance to protect their privacy and just didn't take it is really not true. Some users' privacy was violated the instant they logged in, and giving them tools to help them clean up later (and not telling them about the tools!) does not even remotely help.
