I followed the instructions in How to add a BlogMap to your blog and added a BlogMap (above the Flickr Section on the sidebar). BlogMap is a service from FeeMap that displays the geographical location of a blogger. It is neat. However, if your location is outside the U.S. you can Google to determine your latitude and longitude. BlogMap also gives the locations of your neighbouring bloggers. How does it help? I don't know..I don't network with other bloggers but I thot it was cool and added it!
