/lit/ - Literature

I wish scifi was as well organised and easily to follow trends as with fantasy. Fantasy seems to have much more decipherable work, with plenty of big series by authors who've written tons.

I just made the strange journey from Dune, to Foundation, then weirdly onto Hyperion then Revelation Space, all under the "Space Opera" title, but they were all so wildly different I couldn't help but feel it wasn't a good recommendation.

Am I just autistic? Specifically what SO should I read to get a good feel of the sub-genre, but more generally where's a good flowchart or direction-ed reading list for scifi categories?
