PersonMaps Google mashup combines mapping with White Pages

Always the mashup fan on the look for cool new apps., check out PersonMaps at http://www.personmaps.com. This mashup appears to combine the white pages, or a similar directory with the Google MAp API, enabling fast, simple location of addresses and phone numbers. In testing it seemed to yield 0 hits whenever I provided a first name along with last name. Using only a last name along with a city and State generally provided an accurate hit with the results I was expecting... quite cool. Once found, the "zoom to" action is nice, providing a tight zoom on the address and lists a box with the full address.
