I am trying to get some better direction in the wiki as it pertains to concepts and I have identified a few kinds of concepts that we use:
Publication - Concepts as to how comic books are put together, like concepts on TPBs and letter columns or stunts like the Tron Legacy Covers
Comic History - Pages that look at the history of comics like DC Explosion and Implosion or Roy Lichtenstein Pop Art.
Artistic - Things about how artists do their work such as Kirby Crackle or Ben Day Dots.
Genres - Straightforward, things like romance or post apocalyptic.
Themes - Things like drug use in comics, homosexuality.
Comic Cons - These generally go as concepts (including cosplay)
Teams - Some teams go as comics instead, with pages like Zombies or Robots or Aliens.
Universes - I am trying to expand on this, but this should be things like Star Trek, Star Wars, G.I. Joe, Transformers and so on.
In comic concepts - Things that exist inside of comic universes, like multiverses.
Are there any big sub-groups that I am missing? I am thinking of trying to get these better organized and making them into editable lists to make them more easy to sort through.
