As this rolls out, in your Facebook privacy settings, you will have a single view of all the applications you've authorized and what data they use. You can also see in detail when they last accessed your data. You can change the settings for an application to make less information available to it, or you can even remove it completely.
I think this will surprise alot of people - alot of apps use your personal data in ways the general public never dream of!
