Manga and Comic don't clearly indicate the distinction between when to use their respective tags on their wiki pages.
As near as I can tell, the distinction (based on the wiki pages) is supposed to be whether something is published on the web or actually in print, with web-published stuff going under comic (or at least it talks about that, while manga basically says nothing beyond defining the term.)
But it's not 100% clear, and even the line between published and unpublished can be unclear nowadays, with things high-quality enough to be published sometimes just appearing online (not to mention relatively low-quality or sketched-out doujin and eromanga, 4koma and other more specific tags that are not referenced in either the manga or comic pages, which also don't reference each other.)
Should manga and comic be separate at all? If so, what should be the distinction between them? I don't really care one way or the other, I'm just not sure which should be used where right now -- there's some hints of a distinction in comic, but the wiki should probably make it clearer when to use which, if they're going to be separate.
Should some of these tags imply others? Should doujin, eromanga, 4koma, etc imply either comic or manga?
