And yes, I appreciate having an SF section in bookstores, but they also take the "literature" out of everything else and hide it so those of us who want our space fic don't have to paw through Faulkner and Joyce. Ever notice how the SF section is prominent, but the so-called great works are buried with the cookbooks?
Because way too many folks are reading SF (or Fantasy) almost exclusively because they think it is more FUN to read. To me, a lot of SF is like eating highly calorated air. Look, I've read and enjoyed a lot of SF but at some point I decided to check out literary novels.
Nothing wrong with reading Asimov or Vonnegut but how about reading them AND James Jones AND Robert Penn Warren AND Ralph Ellison AND Tolstoy? As to the SF ghetto, way too many people volutarily put themselves in that ghetto by reading SF and Fantasy almost exclusively.
