I live in Hong Kong, and at least from my observation, light novels and comics are quite different things in Asia. However it seems that on sites like MAL, which is not of the Asian origin, they categorize light novels and comics as one.
Are light novel and comic seen as similar things in English speaking area? Or is there any special reason for services such as MAL to decide light novel and comic should fall under the same type?
I also noticed that this site is named "Anime & Manga", but also contains a light-novel-production tag. Hence the same categorization seems to happen here as well.
