As I and Seem stated, there is very little point in uploading doujins unless each individual page has some merit. Chances are with most doujins that half of the pages would never be worth uploading on their own, so unless you can view each individual page and say "I'd upload this even if I didn't have the rest of the doujin", you shouldn't be uploading it.
Instead, the simple solution would be to post the cover and source it with a rapidshare of the complete work. That way, the people who want to read the whole doujin can do so without using up an entire results page of space. Once again, this doesn't apply to doujins in which every page works as a standalone piece.
This would also mean no more uploading of hard-translated doujins that already exist on the site, no matter how good the original is. It's extremely stupid to have two versions of a doujin uploaded here when the only difference is the language. Just put a link in a comment on the original for the translated version.
Honestly, there are dedicated sites out there that have simple and intuitive searching and browsing features for doujins, and danbooru isn't one of them.
That's my two cents.
