AIM, AOL's instant messenger, is more open every day. AIM host team (whatever that means) created two kml files that let you visualize interesting real-time information about AIM users in Google Earth.
One of visualization displays all the conversations started in the last minute as connections between two or more cities. The other one shows the most popular AIM users. By looking at the map, you'll notice that Germany is the only European country where AIM is really popular.
