OpenStreetMap is a collector's dream. While there is a finite set of stamps or coins, there are millions of shops and beauty salons, and new ones are opened every day. Yay, collect them all for the map! (And make the map better in the process, of course.) Alas, this task was made tedious, virtually impossible by our current tools. Not as much for adding — but for updating the data we've already collected, and finding what's missing. I've talked many times of this problem, and this year I think I've fixed it. This year changes everything for how POI are handled in OpenStreetMap.
