If they don't exist already, I think there should be wikis for good and bad comic books, like Amazing Comics Wiki and Dreadful Comics Wiki. Examples:
Amazing Comics - Action Comics #1, the Simpsons Comics, Astro City, etc.
Dreadful Comics - Avengers #200, Spider-Man: The Clone Saga, Amazons Attack, Novas Aventuras de Megaman, etc.
What do you think?
