Quite recently we gave you options to disable Google Buzz emails and Buzz update counts in Gmail. However. it turns out Google does provide a much more easier to disable Google Buzz completely for users who do not want to use it.
If you are a user who has no use for Google Buzz, login to your Gmail account and scroll down to the bottom of the page. In the footer links you will see a link which says "turn off buzz".
Just click on that link and Google Buzz will disappear from your Gmail account forever. If you want to turn on Google Buzz again, scroll down to the bottom and click on the "turn on buzz" link.
