There’s probably something wrong with the fact that I get little buzzes of excitement when mobile apps that I use get an update. This morning’s Google Maps for Mobile update was even buzzier than normal, though, because it introduced a new feature that people have been clamoring for for some time.

The new version of Google Maps for Mobile features a service called Latitude, which uses the GPS in your phone to track your location, and the location of your friends, much like Yahoo’s Fire Eagle service. You can see exactly where your pals are hiding out, and there’s plenty of built-in privacy control too.
