Hi! You're rather curious! This is a maps server for UsedEverywhere.com using maps from OSM. We use PostGIS, mapnik, and some other pretty awesome stuff which is freely available to the public. I suggest you play around with it, it's pretty cool, mad props to all the people who make this possible!
However, since this is just a map server, I'm going to redirect you to UsedEverywhere.com. so you can get more information about who we are and what we do. Happy Hunting!
