Couch Potato Geohash
The following users have won the Couch Potato Geohash Achievement. This achievement can be attained only when the place where you live is exactly under the coordinates of a particular day. This is incredibly lucky, and the chance of this happening to you, is the area of your domicile divided by the area of the quadrangle you're in. Assuming a spherical earth of R = 6378km and ϕ = latitude the equation for a quadrangle is:
A typical apartment dweller in Denver, CO, has a chance of around 9e-5; a bit worse than one in 10,000.
If this does happen to you, you are required to throw a mad-keen party at a day's notice.
This is one of those things that probably won't ever happen, but how cool would it be if it did?
