There was this website that I signed up for a while back called dodgeball that had this nifty idea. Say you are out on the town at a bar, but you wanted to see if any of your friends were nearby, so that you could meet up with them. You flip open your cell phone, type in the appropriate message, and voila, you can find any of your dodgeball friends in a 10-block radius.

I like Google as much as the next guy, but I can't help to be moderately concerned that this very smart corporation can track my physical location. I bet with some quick coding, you could pretty easily align dodgeball with google maps and, voila! Colin-maps is alive.... All you have to is type my name and you can find me wherever I am, map and satellite image included (my girlfriend would LOVE this...) . They just did this in 24—but that was one, a tv show, and two, the military. To be able to get tracking services online and probably without charge would just be pretty nifty—and a little disturbing.
