How taking pictures through windows  can inadvertently reveal your location
Isn't revealing your location the whole point of taking a picture from your hotel window and sharing it with the world on Twitter? I wouldn't be too surprised if I posted "I'm in Miami, and here's a view from my Hotel window" and someone was able to tell me the Hotel name and which side I was staying on. Infact, I'd be more surprised if someone couldn't!The techniques used are not particularly ingenious here, especially as most of the photo's seem to depict some obvious landmarks to provide an easy point of reference, especially when given the extra information to focus on a specific location.
