from Mark over at AHOT

A few months ago Google quietly opened up an interface to a white-pages
lookup service.

If you pound your phone number into Google (separators are optional), then
if the white pages listing is current (and your number is listed) then it will pop up your address along with a link to Yahoo/MapQuest maps and directions.

If this bothers you, you can have the listing blocked.

- Click on the Phone icon to the left of your name
- There's a link on the resulting page to: http://www.google.com/help/pbremoval.html
- Fill out the form on that page

Remember also that Google isn't the only service like this. They suggest that you hit up the others as well, and give you this link:

http://www.google.com/search?&q=reverse%2Bphone%2Bbook%2Blookup&btnG=Google%2BSe

Update:

you know the meme has surfaced when it hits the NYT
