By default, your activity on Yahoo! Buzz is public on Buzz.
This means the following. First, when you are the first person to "buzz up" a story, we will feature your display name and avatar next to that story within Buzz, along with a link to your Buzz Activity Page. Second, your My Activity page will be public. This page includes your total number of “First Buzzers”, “Buzz Ups”, “Buzz Downs”, and “Comments”, and a list of the most recent stories you have acted on. If you do not want to make your Buzz activity public on Buzz, please visit your My Activity page and uncheck the box that says "My Buzz activity is public on Buzz”. Please note that your comments on Yahoo! Buzz are always public on Buzz, and you cannot edit or delete them.
As well, by default, the stories you buzz up and comment on will be broadcast as Updates to your connections on Yahoo!. Updates are mini-stories about your online activity, such as pictures you upload, reviews you write, items you rate, etc. You can control the types of updates you share on Yahoo! by visiting the Manage My Yahoo! Updates Page. As well, you can control your display name and avatar (as they will appear on Yahoo! Buzz and other Yahoo! properties) by editing your Yahoo! Profile.
Please note that while any Yahoo! user may interact with Yahoo! Buzz, for the time being Buzz Updates are not public for users under the age of 13.
