I use google reader and I have noticed only new shared items on Buzz posts. I.e., it did not automatically 'publish' old stuff I have shared. Seems OK with me.

I use google reader and I have noticed only new shared items on Buzz posts. I.e., it did not automatically 'publish' old stuff I have shared. Seems OK with me. In fact, I kind of like it. Only complaints I have are: 1. Missing tagging functionality (or I haven't found one) 2. No centralized 'privacy control panel'
