From a privacy standpoint, what effect does this have on us? I kind of cringed at the thought of my house number being spread around the Internet for strangers to solve. Then I realized I don't really have a problem with people solving my address so much as I have a problem with Google having a database of photographs of everyone's house.
My house isn't necessarily invisible, but having photographs of my (and every other house) sitting in some company's database makes me uncomfortable.
It's kind of like those cars that drive around recording everyone's license plate. Sure, that information is sitting out in the open anyway, but streamlining the collection of that information gives me the creeps.
Are my concerns unfounded?
