The subculture and legal controversy of fan fiction:

Fan fiction, as a consequence, has become highly visible to fans, non-fans, authors and media companies alike. A poster child for the new ethos of participatory culture, it is at the heart of a ‘free culture’ movement which celebrates the making of user-generated works and ‘appropriation art’, and seeks to liberalize laws to let individuals remix and mash-up others’ copyrighted works to create their own.

Fan-fiction is the lurid yet wondrous ghetto of the read/write culture.
