There's an interesting article in The Guardian today about the history of fanfiction, mentioning a few of the Twilight authors and tracing its development from, er, the Bible through to Jane Austen (those published 'sequels' to Pride and Prejudice by other authors), through Kirk and Spock, Harry Potter and Twilight. The comments are quite interesting too, although, I am frankly disturbed by the banner of Captain Kirk's naked chest...just to warn you. Also, Justin Bieber fanfic... squick.
So....interactive part: what other fanfic genres are or were you into?
What fanfic relationships really, really, turn you off?
I started with Faith and Buffy (Faith being on my laminated list, lol*).
