The way that the application uses it is by allowing you to check where your friends (people you follow) are, based on the location of their last tweet. It will display your tweeps using Google Maps and indicate their location.
The best part of the application is that if you turn your camera on you will be able to see tweets relative to your current location. So, for example, if you have a friend that is physically to your west tweeting, you will be able to turn your phone to the west and see his tweets there. And If a tweep is close by, it will display an arrow pointing to their direction and their distance from you.
Of course, people will have to turn on geolocation on their Twitter accounts to get the most out of this application, and currently only the 3GS is supported because it utilizes its compass facilities.
Now if you are able to ignore the creepy factor of strangers knowing where you are whenever you tweet, this would be a great app. Especially if you follow a lot of local tweeps, and enjoy bumping into them unexpectedly (… or stalking them).
