MEMBERS FOR YOUR SAFETY...There is a new privacy setting called "Instant Personalization" that shares data with non-facebook websites and it is automatically set to "Allow." Go to Account > Privacy Settings > Applications and Websites and un-check "Allow". Please double check
Also YOU may be careful with your information but your friends may put you in jeopardy. Every time your friends join a website using facebook connect, play a game or use a cutesie application to send something they give permission to access ALL of their friends information. You can make sure your friends aren't a liability by going to Account > Privacy Settings > Applications and Websites > What your friends can share about you (EDIT SETTINGS) uncheck everything (unless you don't mind third parties that you never authorized look at your private information and SAVE changes.
You might have to repeat it a couple of times because even though I kept clicking on "save changes" it took nearly 3 tries to get it to stick. Every time I would click on save changes go to another page on facebook and return to the setting they were still checked.
Here is a pic of what it looks like
Here is the text in case the picture above isn't clear. taken from the application and websites privacy settings.
