We used to run a map website called Pudland, which was a pretty busy WC2 community. I also wrote a map utility called Puddle that randomised maps, rotated them, etc to make them a bit more interesting; I remember reverse-engineering the map format to do it, which was a fun exercise. What great times they were.

This has existed for years:

GeoHash is cool - but the hashes don't lend themselves well to stemming for use in text-based searching. This improves on that.
