In Western cultures, dōjinshi is often perceived to be derivative of existing work, analogous to fan fiction and almost completely pornographic. This is partly true: dōjinshi are often, though not always, parodies or alternative storylines involving the worlds of popular manga, game or anime series, and can often feature overtly sexual material.
- From WikipediaPersonally I'd think it would be interesting to see how much of the community reads doujinshi.
