Sprint has a massive program letting customers see where their friends are through GPS-enabled phones. Because sometimes people aren't using Twitter! Obviously this service (also coming out from Verizon) is huge with the kids, says the Wall Street Journal, because they're savvy enough to get that only approved friends will see where they are, so this isn't a stalker machine. The real danger is seeing long-distance loneliness in real-time.

I'm one of those people who never makes plans and thus ends up calling six people at eight o'clock and ending up eating dinner alone. For a while, I sent mass dinner invites on Twitter, but that only broadcast that I was a loser.

Now imagine I know who's close by. Thank Jesus I don't have GPS, or I'd text people saying "Dude, you're just four blocks away, come eat with me!" So unavoidably awkward.
