^Another agreement from me. I also write because I enjoy it and also choose subjects (and races) I like most. But I know that I'd also like some audience, because writing into nothingness would take all joy of writing away. So while not writing purely and only for the readers, trying to guess what they'd like, I think a lot of fan fic writers still would like someone to read and enjoy their work, even if it's written for fun and from their internal need of writing stories.
