Google Earth is a cool concept, but it still has major bugs to work out. It links to their web database, so if an address appears in a website the map finds things that way. For example, the other day I was looking for an address; someone who lived at that address was mentioned in a newspaper article, with his address; Google Earth then zoomed to the address of the newspaper office instead of his address when I entered his address. I couldn't get it to go to the proper location.
