Geomaps of social software networks are sprouting up all over the net. Now there’s GeOrkut, a density map of the Orkut population of users who input their physical locations. This project might be the most detailed of them all, as you can even make out some highway systems that lead to member’s cities and towns. Even Friendster has an interactive mapping tool with Ben Russell’s Blogosphere – more info here. Next up would probably be to integrate Mapquest with the US postal service and email to see a plot of how many physical letters vs. emails reach their final destinations.
