Now this is useful. Yahoo has a button on its maps that shows WiFi hotspots. Very, very nice.
I love the integration between Yahoo maps and Google. Too bad their competitors. I guess Google will have to buy Mapquest. Mapquest maps don't impress me; what I really want is tight integration between search, maps, and my personal data. Even Yahoo has done a poor job of integrating the "address book" and the "map location" list.
