I think I understand your point, but the system is optimised for 4 actors. Advertiser - Ad Network - Publisher - Consumer In the end it is multiplication of happiness factor for each actor optimised. It is basically explore/exploit algorithm + trying to predict your behavior with similar segment of people like you. That's why you are mostly stuck in exploit phase, cause explore part is costly to other actors (even negative ROI)
