This combination made by a kid at Clemson (dang Tigers) combines google maps with the white pages. Type in an address, get the map and a list of names, addresses, and phone numbers of the other people who live on the street - at least those who are listed in the telephone book?

When using my street, the app kicked back about eighty percent of the folks - thankfully my address/phone number was not among them, but our phone is unlisted.

Privacy? Seems that horse done left the barn a long time ago.
