These instructions are incorrect. Clicking "turn off buzz" will only remove the Buzz label from your Gmail account.
You need to either (1) delete your Google profile first; or (2) if you want to keep your Google profile, edit your profile to not display followers, then delete any buzzes you may have posted, then removed connected sites, and THEN click "turn off buzz".
I thought one of the complaints was (at least until recently) "disabling Google Buzz" mostly turned off your controls and notifications- but did nothing to prevent others from following you.
No sarcasm font, but I hope everyone gets the point.
EDIT: it wasn't meant as a serious guide, but reading the comments I understand it might be taken as such, so added a link to the real instructions now.
