Found something new (to me) on the web. GeoURL is a place that lets you do location/URL lookups. Adding your blog or site is pretty easy. Just look up your location (latitude/longitude) on a site like the US Census Tiger Map Service, add a couple of meta tags to your index page and submit it to the GeoURL site. They'll add it to their index in a litte bit, and give you a link showing other URLs in your geographic vicinity. Clicking on the map at GeoURL gives you a big long list of websites in the vicinity of where you clicked.
There's another site, GeoTags that does something similar also.
Kinda neat I think. Then again, simple things amuse me.
