I had an idea that maybe you could make a little extra money when mapping, why not? It could be nice for kids especially, maybe some of them wouldn’t be interested in mapping otherwise, but money could be an incentive.

The point of OSM is to give knowledge to people for free— not to earn money off of it. Don’t join OSM if profit is what’s in your mind. It’s the passion that drives people to make such beautiful maps for free in OpenStreetMap. Not profit.
