Or, how about not saving the location in the URL at all when moving the map? I guess there must be a reason why none of the mainstream map webapps does something like this...

It allows you to copy and paste the url to link someone to what you're seeing. It's a good thing if sone right.

Also, google maps changes the url as you pan and zoom.
