And yes, you're right about the money motivations not necessarily being a bad thing, but I also think, from a game theory perspective, people like to reward cooperative actors more than selfish actors.

People would most likely vote up content from authors who are truly more concerned about the benefit of the whole network than about their individual reward slice.
