I wanted to post a quick response before I forget.

GasBuddy

My friend somehow has GasBuddy integrated with his iPhone. He used his iPhone map to find the lowest diesel fuel around us. I know that google is the default map on his phone, I wonder if maybe there's a way to tie GasBuddy maps in with this frontend application you've made.

This is a very cool app you've setup, so I hope these suggestions don't seem like a lack of appreciation. I'm just throwing out ideas that might make it more cool.
