"OpenStreetMap is not about crowdsourcing, OpenStreetMap is about community collaboration. This is not you being a mindless crowd adding data to some big company’s map. This is about you putting in data in your own neighborhood, working with your neighbors, working with a larger community to refine and make a really cohesive map. That's the kind of experience that was so successful with Wikipedia." — Atlantic Cities
