The best part of Bitchat using geohashing is that I now know that geohashing exists.

I had heard of geocaching (which is a natural fit to gamifying aspects of geohashes) but I had never heard of geohashing itself before and it's fascinating.

I've had a long love affair with maps, mapping, GIS etc but I've only ever used Lat/Long for location finding. This geohashing thing is such an easier way to think about locations.
