well there are many roads to mecca, however the way I personally make money from facebook apps is this:

create a useful app, which targets a niche, and is viral in nature and lets the people know something about your tastes. Pimp the app in relevant niche forums, groups and so on..

say you are into movies / video-games- you might make a Facebook app called ("what movie i am watching", or "what i am playing")

the app will put the info into your profile, along with a link to amazon where the user can buy the movie / game or whatever (obviously using MY amazon affiliate link)

squids in.

incidentally in case anyone wondered you host the FBook App on your server, and use your own dbase etc.

I'll let u know if I manage to make $1,000,000 a week from a facebook app lol
