This website was just opened and discussed by lifehacker.com:

Gas: Fuelly Shares and Compares Your Gas Mileage

It keeps track of all your Fuel use, and allows your friends to track along with you. It's a neat concept, and I like it. Data entry is OK from the iPhone...

But if someone could build a real quick and easy app that I could use to quickly type in the info (even if I dont have signal) that would update the website... that'd be awesome! It would just be an easier form factor than logging into the site, browsing a page or two over... and then entering all the info on a website...

Just an idea.... I know there is MPG, but I can't get it to install... and I like the idea of my info being backed up on a website where I can access it, or share data with my friends.
