I just wanted to thank Desiree for the heads up and mention that a story about a burglary in our paper this AM sounded like robbers actually do use this tool. Is said in our paper that many houses in Philly were robbed last year, they would call the houses repeatedly and when they didn't get an answer go online to find the address. I've sent emails out to everyone in my address book, does anyone know of any other search engines that allow you to find an address with just the phone number?
