His main argument is that being a self identified a fan gets to enjoy the benefits of community, but are discouraged by the label to create stories and worlds of their own.
I couldn't disagree more. I am a fan. I have always been a fan, and I participate in multiple fandoms, and that has not stopped me from creating my own worlds and stories. I would even argue that this exposure forces me to figure out how I can be more original.
I started writing fan fiction, and it was a great place for me to learn some of the fundamentals of story. I will not repeat my old "fanfiction is what culture is" sermon again, but I still feel that way.
Fandom is the a world of like-minded people who help me discovery new fiction, music, and games. They expose me to new ideas, and challenge my preconceptions.
Fandom is, as Martha Stewart would say, is a good thing. /rant
