I recently got an email, a forward that I didn't mind. It was very frightening, actually.
Seems that if you type your home phone number into the address bar of your browser, Google (or something) will bring up your name, home address and a map to your house. This can also be done with Switchboard.com's search by phone. I tried it on someone I know, and it worked.
I guess if you click on further (both versions), you can remove your listing. I would highly suggest you do this. How many times have you had to give out your home phone number? What about your kids? (Likely, they have it memorized, and won't be too hard pressed to give it when asked.) Scary.
Another reason Dr. B and I are glad we are land-line-less. I tried my cell phone number. Came up unknown. For the only time in my life, I am glad to be unknown!
(And then I go posting pictures of myself on the internet, but whatever.)
