Rewards might be what gets someone to notice a Social Mining campaign But they don't decide whether the campaign was actually interesting If the project has nothing worth exploring, the task quickly becomes something to finish and forget A useful product changes that experience You start researching because you genuinely want to know how it works. You might even keep looking after you've already found enough information for the task That is the point where participation becomes more meaningful than the incentive itself I think @TheDAOLabs has an interesting opportunity here, using #SocialMining to put real projects in front of people who are willing to explore them properly
