What makes a story worth reading?
As a writer, and as a reader who has plowed through thousands of stories over the past decade, I've developed a fair idea of what works and what doesn't. Some writers cast a spell on you from the first words and maintain that trance until the very end. Others have good ideas but break momentum with clunky prose. Some turn a phrase skillfully, but their plots don't hold interest.
I find that science fiction authors are more likely to hang their tales on plot to the exclusion of other factors. This is part of the reason our genre is much maligned by the literary crowd. On the other hand, the literary crowd tends to commit the opposite sin: glazing our eyes over with experimental, turgid passages.
A few authors have managed to bridge the gap: Theodore Sturgeon, Avram Davidson, Daniel Keyes. And, in general, I think the roster of science fiction authors, as they mature, are turning out better and better stuff.
Sadly, Astounding is rarely the place you'll find them.
