I've been reading up on how to get stories (I'm aiming for flash fiction at the moment) published. Recommendations I've seen are to separate publishers into tier 1, tier 2, etc., and send down the tiers until something gets published. I'm only aiming at tier 1 at the moment. I'm told (or: read online) to expect at least 10 rejections for every acceptance, even if I'm going down the tiers and doing everything right. Some published authors seem to recommend immediately resubmitting stories that are rejected to another publisher/web magazine. Without, it seems even a rewrite. Is this really a good and reasonable strategy? It just seems scattergun to me. What would people on here recommend?
