[Internet] Competition and improvements

So Google Maps gave us zooming without web page refreshes. Today I just discovered that Yahoo Maps also incorporated this feature into its offering. You still can't drag the map around like Google's, but at least when you zoom or move around (via direction buttons) in Yahoo Map, only the map is updated, not the entire web page. This is actually not hard to do in DHTML, but I suppose Yahoo just wanted that little pressure (or idea) from its competitor.
