Virtual goods are entertainment. Granted, I don't play Farmville or any other game (and I do find all those updates on fb annoying). I assume the pricing is pretty transparent. Just as I find buying tickets to sports games to be a waste of my time (with a particular net negative on baseball), to each their own.

Affiliate marketing however, is where the assignment of value somewhat more arbitrarily/discreetly decided as it depends on actions of third parties. Besides, it's about pointing out an opportunity that exists - and in that light, even if I were take your position, you could make the argument that it's one that he's very qualified to make.
