On the "Privacy Settings > Applications and Websites" page, there is a "What your friends can share about you" listing. This is the really fun thing about all this... they seem to know how to put just enough controls here and there in the labyrinth of settings so that few specific complaints really stick. While, at the same time, they never unify the intent of the controls into something that the user can see all the implications of their settings and then set them the way they want. To me, this just cries out for some visualization. Maybe some nested circles (each circle representing a friend group) around the user in the middle, arrows (representing the types of information that is shared) radiating out to the furthest circle which can see that information.
