While playing with the longitudes and latitudes of the Talk Maps users I noticed that putting them in a KML file creates a fun toy. Google Earth can read this format and displays all online users in a 3D virtual earth together with all other placemarks. Earth has better data and streams images faster that Google Maps.
Try playing with the refresh interval.


Also notice that the links of the users appear as links in Google Earth and they are opened in an internal browser (yuck IE). So this is some kind of browsing by geographical position. Like.. "let's see what the guys from South Africa are thinking today..."

Update: In Google Earth: Add -> Network Link -> Location: "http://www.epigoon.com/maps/kml.php"
