Of course, the real question is: does reading speculative fiction give me any kind of insight into what sorts of things other people might like to read? And can I attract any kind of quality writing if I don't pay for stories? And am I really one to judge other writers if I haven't published (or really written, for that matter) any speculative fiction? And how can I start a magazine when I know it won't be the best?
Some of the above questions are rhetorical. I'll leave it as an exercise for the reader to determine which those are.
