Its a cute idea and all, and of all the best intentions. However I would advise people to be more aware of your personal security. This map thing easily allows for some serious knowledge pertaining to your location. For instance, I zoomed right in on Mazerstevens street and house, were I the criminally minded fellow, having looked at his beautiful system I might decide to aquire it. Now not only do I know his street and house I have great satellite imagery to utilize in getting there.
My recommendation to everyone who uses this would be to only list your state/province, and at most city. Throwing in your zip/postal, with street and address is allowing a serious invasion of privacy.
Perhaps the mods can make this sticky thread a "member only" section, at least that way we can limit the amount of transients who have access to such personal information.
