I'm not sure if you already do this, or if it's on your roadmap, but I would like the option to find specific products my friends have recommended. For example if I want to purchase a new camera, I would search "camera" and it would show which cameras that my friends (or just other refer.ly users) have linked to. I guess you could also go as far as having users review products they've purchased and have a public "review" system, the incentive for users would be: if someone finds a review you wrote and purchases the product through the review then you get rewards, it would further allow people to not need their own network outside of referly to promote their URLs, but I have no idea if that extends beyond what you're trying to achieve with referly.
