While I agree it's disconcerting to see your home pop up so easily, it is pretty much the way of the world today. All anyone needs is your address and they can do the same thing with Mapquest. Heck, they can even go to satellite sites and look at maps that show your "real" house.
Something you might want to keep in mind is not sharing too much information over the Internet. While most people are "friends" there are always those looking to use information. If you share your real name, town, dates you are going on vacation and that no one will be home....you have shared too much information.
