I've read just about everything by your six "normal" sf authors. Sometimes, I want my wasted time back: I think most of the post-
Moon Is a Harsh Mistress novels by Heinlein were very nearly unreadable. I also tend to wander around the genre pretty broadly, although I do avoid military sf (Ringo's writing, especially, has left a very bad taste, and I stopped reading David Drake after the, imho, incredibly stupid "Hammer's Slammers" books), and cyberpunk (I do not like William Gibson's works). I think that the SF genre has gotten much better, in many ways, since the "Golden Age": the writing tends to be better, especially in regards to character development. Asimov was probably in the "weird" category when he started writing -- his near-total absence of aliens was, I've read, due to a disagreement with John W Campbell, who held definite "human manifest destiny" ideas that Asimov, as a Russian Jew (see:
pogrom) found unacceptable (Asimov did not, apparently, think that Earthlings would be all-conquering forces for truth and justice against vile, aggressive aliens).
So have I read the sf authors the OP would categorize as "weird?" Of course -- they're some of the best sf writers out there.
