I had a though recently. It would be neato to have some open source, crowdsourced world database of item locations, where you add this sort of information.
Tagged search of a store, where certain items are. What’s stores in a city sell X item. That sort of thing.
Call it “WorldDB”, bake it into OpenStreetMap.
No idea what the legality would be, but I would LOVE it.
May write a post about it at some point, as I am no programmer.
Does this mean two females are able to produce sexually viable offspring?
