How to disable Google Buzz completely?

Exactly one week ago, I posted a tip on Disabling Google Buzz. It talked on disabling Buzz through merely removing it from showing in Gmail.

Google recently added a new option to disable Google Buzz integration in Gmail and delete your Google profile and Buzz posts. It will also disconnect any connected sites and unfollow you from anyone you are following. This unfollowing process will also unfollow you from the ones you follow in Google Reader, which is rather unnecessary.

To find the new option, go to the profile editing page, scroll to the bottom of the page and select "Delete profile and disable Google Buzz completely".
