Yeah part of the issue is simply that S&S as a genre has basically been erased by "epic fantasy" in the modern fantasy-reader's consciousness. If you're not publishing a trilogy or even better a series of dead-minimum 300, preferably 500-page plus novels, do you even write fantasy, bro? Certainly the average fantasy fan today will say "No". The idea of reading short stories (THE HORROR) is particularly repugnant, when they're used to immense rolling novels. I mean, I can't entirely blame them - a lot of fantasy works really well in that format, but it also means that older S&S doesn't stand a chance. Even amazing writers like Le Guin, who did write multi-book series are gradually getting forgotten because there aren't literally thousands of pages of blather about Sparrowhawk, only a few hundred, and it's insufficiently power-fantasy-ish. And it's becoming increasingly clear that quantity might be more important than quality though I will not name names re: the authors making this evident!
