If only 2% of the participants in any given Internet system contribute, why do they do so?
Other incentives besides the content value of the digital goods?

Public Good

Social Psychological Selective Incentives
Social psychological processes could give small, positive feelings to contributors
Social psychological processes may be small, but they can have a relatively powerful effect if the costs of contribution are very small as well
