>>94649You haven't read many manga, I guess? There are many manga that contain pages full of text. Some even only consist of a few avatars that don't change and speech bubbles.
Manga, books, visual novels are just different ways of telling a story, and the borders can be very blurry.
You could represent this thread as a book, by only using the posts as text.
You could also represent this thread as a manga by making a page/panel/speech bubble out of every post and maybe adding the images of each post.
Often, in reality, as opposed to theory, things simply aren't as distinctly different as you'd like to have, friend.
