Fanfiction article from July 2005 "Wired" magazine
Interesting article, particular as the author points out that fanfiction might become a cottage industry someday. He uses the example of the novel "Wicked" in his article, but I also thought of Jasper Fforde's Thursday Next series. He has an original character (OC in fanfic terms) who's interacting with dozens of other characters created by other authors.
Comments, discussions welcome.
