There is something about privacy that we all understand in an intimate way and yet seem unable to apply broadly. What is it about our conceptions of privacy that can make an individual angry when a companion reads a diary and yet allows that same individual to make a wealth of information available on the internet? Is there a difference, in kind, between the two forums such that a post online is ‘supposed’ to be read while a diary is not? It is hard to imagine a substantive difference between revealing online activity and a diary.
