To clarify, the "anime" and "manga" categories mentioned in the post are actually structured as format categories and NOT fandom categories, which is why we were pondering Anime/Manga as a separate Fandom by Source Community category--in other words, maybe it should have a fandom category instead of the current structure, where the intended use of the categories is unclear. Already under Fandom by Source Community we have SF fandom and Furry Fandom, and if we created a "media fandom" or "animanga fandom" category, that is where it would probably go. Or we could just move the current Anime and Manga categories there, where they make more sense.
The current parent category, Fandoms by Source Text, has a number of different format subcategories that basically list titles of source texts--Television, Books & Literature, Film, Comics, Cartoons, Anime, Manga, Games, Radio, Theater, Real People. These categories were instituted before we got fandom categories, and now we also have individual "fandom by source text" categories all listed together under the main category, not sorted by format or fannish tradition. So, rethinking how we were using the format categories seemed like a good idea.
