Geohash
From Geohashing
A geohash is a random coordinate generated across the world1 every day by an algorithm as described on XKCD comic #426.
These coordinates can be used as destinations for adventures, à la Geocaching. They can also be used for local meetups.
For a little more interactive discussion consider joining the #geohashing IRC channel on Foonetic.
1. Europe/Africa/Asia date handling still under discussion, see the talk page for proposed standard.
