MetaFilter founder Matt Haughey launches new webapp Fuelly, which tracks your car's mileage per gallon (MPG), shares that info with friends, and compares your mileage to other Fuelly users. Sign up for Fuelly and add your car's make, model, and year to your Fuelly "garage." Fuelly will display the EPA's MPG estimates for your car (average, city, and highway). Then, each time you fill the gas tank, you record the number of gallons you've purchased and the number of miles you've driven since the last fuel-up in Fuelly (which offers an iPhone-friendly version too).
