I just found this article about a privacy flaw (actually Google tells you this but in case you didn't notice it or you don't want to share your contact list, you should read it) in Buzz (someone could go into your profile and see the people you email and chat with most); http://www.businessinsider.com/warning-google-buzz-has-a-huge-privacy-flaw-2010-2 Also it tells how to bypass it here; (You just basically unfollow people that you don't want to share their e-mail or profile with the world) http://www.businessinsider.com/warn...rivacy-flaw-2010-2#click-into-buzz-on-gmail-1 Hope it helps.
To close your account there is a small link in the footer of your gmail page like Close Buzz or Disable Buzz. By the way Google made a change and put an option to make your contact list private. Second link in the thread explains how to do it.
at morning when i login in my gmail account that time some page show about gmail buzz. i post some buzz also.
Thanks for the great information, its interesting to see that google is trying to pull even more and more information from you every day. All of your searches, clicks and time is monitored and logged by google. Its amazing of how much data is collected by google on just one person. They keep telling us they collect all of tis data for " the best advertising content to be delivered " however its still a breach of privacy AFAIK IMO; Buzz is just another data collection point of google.
