One of the things I have pondered most of my life (beyond "what do women want") is "what is the essential different between something that is Art and something that is not?"
This essay was published in an early volume of the SF anthology series Writers Of The Future around twenty years ago. Back then I thought I understood it perfectly. But now I'm less sure. It seems to me the definitions of "two-way communication" and of "contribution from the viewer" have to be awfully broad for this to work. What do you think?
