I have probably blogged about this at least once already, but it still blows my mind everytime I encounter a reference to it. If you haven't done this yet, you need to try it--if only to see how easy it is for information-literate-trained stalkers to find you. Many streets in U.S. cities have now been photographed. Looks like pictures of my house were done sometime last winter.
Go to Google; choose Maps; enter your address/zipcode. When you get the map, click on Street view in the box that pops up. Now you can navigate by clicking on the arrow in the middle of the street or rotating the picture using the carets (sp?) in the top corner of the view.
Should you ever see a car driving your street with a set of cameras mounted on the roof, be sure to wave and say hello to the world!
