I just read about an interesting new website called GeoURL. They can give you a list of websites for people that are near you geographically. You sign up for their service by giving them your web address (URL) and location (longitude and latitude). Once you’re in their database you can get a list of sites near you.
Anyway, I signed us up for it and added a button (at the bottom of the right column) to the site so you can see websites for people near us.
