I've been using Buzz lightly since inception. I was talking with one of my friends, who I follow on Buzz, this morning, and mentioned that he might want to comment on something another of our friends had buzzed. He informed me that he had disabled Buzz a week or two ago. I found this odd, since I had been receiving his buzz updates from Google Reader and Twitter the whole time, including some tweets from last night. We discovered that even when you tell Google to disable Buzz, all that does is remove it from your own Gmail interface. It keeps on happily feeding any input streams into Buzz and displaying it to anyone who was already following you. When my friend turned Buzz back on, he discovered that some of his followers had commented on things he didn't know he had buzzed and which comments he had never seen.
This struck us as a flaw.
