Strange Horizons is staffed entirely by unpaid volunteers, and that while staff members sometimes contribute nonfiction to the magazine, they do not receive payment for it.
Strange Horizons is currently looking for fiction editors. These are editor positions, not first-reader positions; the new editors will be part of the team that decides what fiction Strange Horizons publishes, among other responsibilities.
They're looking for "people who love short fiction, who are passionate about speculative literature, and who believe that there are a wide range of voices in our field that deserve to be heard. Prior editorial experience is nice, but not a requirement." If you're interested in applying, go to: http://strangehorizons.com/Jobs.shtml
