= Cheap Gas
GasBuddy.com has made Google Maps its new pal. The place for cheap petrol now uses the Google Maps interface to match you up with cheap gas in your area.
Hmm.. I see a marketing explosion about to happen. Housing and Gas are the first to pop up - will we see grocery stores employ this on a local level to direct the "coupon clippers" to the closest supermarket to pinch their pennies to find the cheapest toilet paper?
