As of today, 11/19/2010, there is a NEW PRIVACY setting called "Instant Personalization" that shares your Facebook personal data with non-Facebook websites and it is automatically set to "Enable."
If you want to disable it follow these steps:
Go to Account
Privacy Settings
Applications and Websites
Instant Personalization
Edit or customize Settings
Un-check "Enable"
BTW, if your friends don't do this, they will be sharing information about you!
