There's also the absolutely hilarious take on zoned-out, geekie, weirded, just plain paranoid sci-fi fans, called "Gather in the Hall of the Planets
," by Barry M. Malzberg
- a genius of a writer who just happens to be (unfortunately) classified only
as a sci-fi writer, but his talents are phenomenal. One must have a weird sense of the universe in order to enjoy his work, however. I love his writing.
You might also look at his "Dwellers of the Deep
," about the obsessional mentality of sci-fi fans who must forgo eating in order to have a complete run of a sci-fi magazine.
Sci-fi fans are portrayed as delusional, self-obsessed, and neurotic as hell - but written with incredible wit and humor.
