Gas costs sure have risen lately, at least in the US. With many drivers are seeing prices well over $4 per gallon of gasoline, the time has come to do something about it. The FuelFrog website, as well as its iOS app or Twitter, can help with this. It helps you keep track of how far you've gone, and how much gas you've used, as well as trends for gas prices in your area. Of course, there's also the FuelFrog API which, despite some security concerns, lets you integrate that data into just about anything.
