In some ways its cool, because you get to say "Oh, cool, this is what my yard looks like from above."

Maybe it is creppy when you think that anybody in the world can look at it. But it's alright... you can probably look at their houses too, if you just knew where they were.

I'm not so worried about Google Earth, because that's very inpersonal, just the Street View, which is way too close to home. People going around with cameras in cars filming houses is not cool.
