One of the interesting things about the smart-phone revolution was when companies discovered that people would as often pay for the ability to run a wide range of interesting applications as they would for the latest hardware upgrades. The iPhone started beating out the BlackBerry in some demographics simply because the Apple product had the far wider variety of, and more interesting, apps. Google has gotten into the hardcore app game with its latest Android phones, and for those whose parking karma is less than stellar, Google Labs has an app for you: the Google Open Spot Home. Now you can let people know when you're leaving, and see when they're doing the same. The more open spots you mark, the higher "parking karma" points you tally. (It actually seems like your parking karma does anything related to the app itself, but if you're one of those who like to keep score for the sake of keeping score, I'm sure it's for you.)
If you're running Android 2.0 or higher and live in the U.S., Canada or the Netherlands, Open Spot Home is for you. Click here to download, and good luck with that next spot.
