Worth remembering: Your fandom is not Fandom, by schmevil.
…everybody does fandom differently. Fandom is not fanworks fandom. It is not media fandom, SF fandom, or whatever fandom. It is all of these things and more. There exist fandoms and ways of doing fandom that you have never heard of. Fandom is mindbogglingly huge and varied – I’m constantly discovering new fandoms, and new fannish activities. All of these ways of doing Fandom are valid.
