Useful Google Maps Mashups

Fantastic list of Google Maps mashups. I found nearly every one del-icio.us-worthy.

The one I stuck on my Firefox Bookmarks Toolbar right away is the phone number locator. It allows you to type in the area code and exchange of any phone number (say of a number you don't recognize that just called you) and see where that exchange is located on Google Maps.

I typed in my own number and it says I live several towns away from where I really live, but that may be because I have VoIP and, frankly, it was close enough.
