Not gonna happen IMHO. Facebook is about interacting with other people. Not about clicking on adverts.

Google on the other hand is about finding stuff, which can sometimes be achieved by clicking on an ad.

you're right. i'm sorry i should have been more clear. i was using adsense as an analogy. facebook needs to find its business model X, as google found adsense.

facebook definitely has a potential X that could be as profitable (or moreso) than adsense. but what that is i don't know. i'm sure they do though.

ah ok sure. Perhaps it's some sort of dating/matchmaking system. I can see that working, although that's a pretty crowded market already.
