After reading your post, I thought I'd check it out, since I had also said maybe later. Yep, I'm all signed up, with one follower, who seems to only write in spanish or portugese, and following seven people. The people I'm following, I'm actually, mostly interested in, but this follower, never heard of him.
I go to help, and look for a way to kill the buzz. It tells me to sign in and go to my account and click on edit next to the product I want to delete. Buzz is not listed. Buzz also persists in saying that I have one follower, although I just blocked him. When ever I check to see who it is, it tells me I don't have any followers. Then it goes back to saying, in two places on the page, that I have a follower.
Fortunately, there is a little teeny link in the middle of a bunch of other tiny text which offers to turn off Buzz.
