I am not sure if this has been discussed but Yahoo has redone their maps page to be better than google or msn in my opinion. I think its easier to use by having the search on the left side with the directions to and from form fields.
You can even save the maps into a "My Yahoo" account which is better than using mapquest.
I just wonder where they are getting these categories from on the left side. If they are from the Y directory or from what Yellow pages.
