Roster of Fandoms

It has been suggested to me, by my roommate, that I ought to list the fandoms I belong to. This is probably a good idea, since it may allow me to quantify how bad my problem is. I'm defining "fandom" as the group of fans who follow a particular movie, book series, or TV show, who think about it and talk about it when not watching/reading, speculate on character and plot subtext, and write fanfiction. Fandoms make their favorite stories part of their lives. They may even come up with a cool name to designate themselves.

Anyway, here is my list:

Fandoms in which I am a full, card-carrying member:

The Whovians (Doctor Who)
The Sherlockians (Sherlock)
The Merlin Fandom
The Psych-Os (Psych)
The Browncoats (Firefly)
The Potterheads (Harry Potter)
The Avatards (Avatar: The Last Airbender, Legend of Korra)
The Janeites (Jane Austen)
The Tolkien Fandom
The Avengers Fandom
The Leverage Fandom
The Star Wars (Episodes 4-6) Fandom
The Olympians (Percy Jackson)
Disney/Disney Princess Fandom
The Tributes (Hunger Games)
Pixar Fandom
Divergent Fandom
Chronicles of Narnia Fandom

Fandoms to which I do not belong, but am at least fluent in their language (whether or not I plan to join):

Bronies/Pegasisters (My Little Pony)
Once Upon a Time Fandom
Delirium Fandom
MSTies (Mystery Science Theater 3000)
Trekkies (Star Trek)
The Downton Abbey Fandom (Note: I may become a full member soon)
The Legend of Zelda Fandom
Twihards (Twilight)
The Brotherhood (Game of Thrones)
The Supernatural Fandom
The Portal Fandom
Big Bang Theory Fandom
Pokemon Fandom
Batman Fandom
Battlestar Galactica Fandom

Things that aren't really fandoms (yet) but should be, and if they were, I'd belong to them:

How to Train Your Dragon "Fandom" (Books along with movie; no one reads the books)
Cloudy With a Chance of Meatballs "Fandom"
Rise of the Guardians "Fandom"
Spider-Man "Fandom"

Anything based on any of my favorite books by my favorite writers (Ally Carter, E.D. Baker, Jessica Day George, Orson Scott Card, Brandon Mull, Lois Lowry, Diana Wynne Jones, Bruce Coville, and Margaret Peterson Haddix, to name a few).

Anything based of anything I've written, because it would be nice to no longer be alone in geeking out over my plots and characters. Sadly, I may have a few years (or decades) before this even becomes possible.
