The word via PlanetGS is that Yahoo! has a new update to their mapping tool. Dan Catt has probably the best overview I’ve seen so far. I used to use Yahoo! Maps religiously, but since Google Maps has come out, I just don’t really bother anymore (other than to georeference photos in Flickr). I switch between GMap and Virtual Earth depending on where I’m at (and I just love the Bird’s Eye view). I will say though these Yahoo! maps look great.
Yahoo Maps, now with new logo!
