I am surprised that other people are still surprised about the amount of personal information about people is online.
Today I showed someone a few sites like intelius.com. Type in your name and state and look at what's available. That particular site offers more info for a cost, but a lot of that public/private information about you is out there for free.
Another site I pointed them to is zillow.com where anyone can see your house from the air and see what it's worth today and the rest of the neighborhood.
