Hi, Kay. They used to boost short stories sometimes, but I know people have complained in recent months that the boost channel has dried up badly for fiction. I haven't written fiction here for a long time, but my only recent exception I self-nommed and it was rejected. I think they (rightly) feel their distribution system is incapable of delivering the right kind of stories to the right kind of people, so it doesn't prove popular. Rather than fix the problem (which would be hard, and probably beyond their coders), they have maybe just sidestepped it by not boosting fiction (or poetry) at all.
