From Doc Searls comes a pointer to Heavens Above, a satellite and astronomy tracking site.
Loads-o-information on Lebanon, NH: track charts, satellites, planets, stars, space stations, comets, amateur radio sats, and more. Being the old map geek that I am it wasn't long before I found their page of Geographical Distribution of Visitors (to the site, not from other universes).
I'm still rather partial to J-Track 3d.
