Yeah, I think there are some sites that already do this very well.
GasBuddy is the main one for the US. I've seen one for the UK, but I can't remember it offhand.
On
Fuelly Mobile for the iPhone, we even gather a longitude/latitude when you fuel-up (if you approve it), but we haven't found a good way to map those coordinates to gas stations. We recently talked about it here:
Location Awareness. So with location-aware phones you wouldn't even need the extra form fields if you could look up business names by lon/lat.
I think it'd be interesting to partner with someone like GasBuddy. They ask their members to report prices, and Fuelly members are already putting prices in for their own reporting. They could increase their reporting numbers if we could find a way to connect the systems. I'm not sure what Fuelly members would get in return but it seems like there's some sort of cross-pollination that could happen.
