theodp writes "With the location land rush in full swing, TechCrunch's Erick Schonfeld declares it's time for an open database of places and calls on the Big Dogs of location — Twitter, Google, Foursquare, Gowalla, SimpleGeo, Loopt, Citysearch, etc. — to make it so. An open database that maps latitude and longitude coordinates to businesses, points of interest, and even people's homes should just be part of the basic fabric of the mobile Web. Foursquare CEO Dennis Crowley was enthusiastic about the idea, says Schonfeld, while Twitter founder Jack Dorsey was a little bit more lukewarm and cautious. Time for Larry and Sergey to invite the Families to a sit-down at 37.423021,-122.083739?"
