Keeping track of my activity on Google Buzz: I've bookmarked a Buzz "search author:[name] OR commenter:[name]" (where [name] is julian.bond) It gives me a nice list of all the Buzz entries I've posted plus all the ones I've commented on. I'd really like another operator for posts I've liked. Something like "liked:[name]". Longer term, I really think this should be a tab on the profile page, perhaps as an alternative to the Buzz tab.
