Everybody have a GPS (almost) but useually nothing to use it for. If you have your coordinates, you can now geocode your website and let people know where in the world it is located.
If you just add a few META tags to your homepage, ping a URL, you are up and running.
If you use geourl, you can see sites near hoerup.dk.
A cool thing is that you can actually view the neighbor list in RSS.
