There's also this awesome website here in Norway to show you all kinds of cool, free stuff in the city on a map, like playgrounds, sports and training facilities, community grills, public toilets, etc.
But again the map does not extract these places from OSM, where people has already spent time and energy adding them, and don't give new places added to OSM either. So the map is worse than it could be, OSM is worse than it could be, and everyone needs to do the same work twice or more.
