I feel like you're making an unfair comparison between fiction and non-fiction.
But isn't fiction the same as nonfiction? I don't only read a small set of nonfiction books that come from a pointed search on a single subject. I read what is interested and related to my fields of interest (which is identical to what I do with fiction).
Either the fiction results will suck ("People who like Fantasy also like Harry Potter -- have you tried it?" i.e. not targeted to the subgenre and thus useless) or nonfiction results are possible.
The take home is this: Have a more granular ability to present social lists for both fiction and non-fiction.
If you can detect what type of fiction I like based on others, you can do the same for non-fiction. You can tell that I like certain subjects and people who share those likes might have some overlap that I would also enjoy.
