As of today, the New FB Privacy setting called "Instant Personalization" goes into effect. The new setting shares your data with non-Facebook websites & it is automatically set to "Enabled". Go to Account>Privacy Settings>Apps & Websites>Instant Personalization>edit settings & uncheck "Enable". BTW If your friends don't do this, they will be sharing info about you as well. Please copy and pass it on.
i got this through an e mail from friends.
don't basically care about it since i am not a member of any of these groups, i.e. face book,twitter and the sort...
