I believe that public participation in open source GIS datasets is only limited by UX. The author framing this as “a side quest while you walk” is on to something.
All that said, this is not a competition. It's just fun to enhance the maps and see the enhancements in real life - better driving directions, more naturally shaped roads, sidewalks being replaced with stairs where needed, traffic lights and pedestrian crossings showing up where they should.
The gamification is only a cherry on top. Now I have to go out, score a few hundred edits and maybe grab #2.
