The article left me with a few "Facebook apps"-newbie questions. Hope someone here will be able to answer.

1. How are Facebook apps monetized? Advertising?

2. What do applications use the collected user data for? I once saw a description of the kind of access an application gets to the user's data, and it seemed a bit daunting.

1. Advertising + Virtual Goods (selling "items" or "currency" inside a game for power, pleasure, or status)

2. You can't really "collect" the data. Facebook's Terms state that you can't keep user data for longer than 24 hours. The original idea was that you could use their data to display demographically-relevant ads.
