Dodgeball in Seattle

The Seattle PI has an article about Dodgeball which is mobile social software that allows you to physically broadcast your whereabouts in order to meet in person with frieds (and friends of friends). Turns out that Seattle is the third largest market for Dodgeball. The article profiles friends who are both early adopters and high level users of Dodgeball. From the article we can gather that the folks they are profiling are: most likely gay, work in high tech fields, have a high level of disposable income, and are on Dodgeball constantly. This article also makes it seem like usa of mobile social software is primarily to figure out which bar to go to.

So I'm wondering out there, have you used Dodgeball if so what for and why? And do you like it. If you haven't, does it sound appealing to you or not so much?
