Is your physical location really part of your privacy if you're in a public place? I can understand that if you're at home on the toilet or something you'd want to keep that private. But when you're walking around the city, or going to a shop, those are public spaces. Therefore it's not private information that you would be divulging, as anyone in that location would have that same information. Then if you didn't want people to know where you are online you would change the settings, or just not use the application. This is just another example of Clay Shirky's idea of Filter Failure.
