Yeah - I notice everything's very public with it. But of course,
   anything you do online (even within Facebook's "walled garden")
   is still accessible. It's like it's always been: watch what you
   say to a reporter, the guy next to you in the bar, a
   friend....or, especially -- online. But I don't expect Google
   Buzz to be a facebook or twitter killer. Then again, who knows
   what will catch on next. "
