I think that a better metric would look at how many users there are for each "category" of application, and how many of them are "active users" as designated by Facebook. Kara's point may be valid, but it is based on a cursory glance.
Honestly, it's a complicated mess. I think the Limited Profile feature from before was sufficient; either people saw what you had available, or you hid it. Providing all of these new options just makes it more difficult to navigate.
