I just read a news story and think it's got to be one of the silliest privacy slip ups ever! You take a picture, post it online and anyone with half a brain can track down EXACT location of where the picture was taken
It was gets registered in the "exif" data of a photo and can be risky if you're taking pictures of kids etc. The news story
I tested it on twitter and it KEEPS the data! The only site that seems to delete it is facebook (to my surprise).
Anyways, think twice before posting pics online
