I don't think K5 has either the temperament or the desire to become a workshop for aspiring writers. That's not to say we can't or won't offer good and useful feedback on stories, but it's always been a give-and-take here. We're willing to comment if you (the author) give us something worthwhile to comment on. So I would rather see stories that the author considers "finished," or at least finished enough to try to publish.
Many comments in the voting process have expressed, in no uncertain terms, that they are not interested in amateur-hour stuff like slash and fanfic. Voting will tell, but my advice to prospective story submitters is that your "Kirk and Spock get it on with Xena" story is not altogether likely to shoot to the front page.
Another thing for authors to be aware of is that writers of fiction often invest a lot of personal self-esteem in their works, and are heartbroken to see them criticized by someone who doesn't have any concern for their ego. Commenters here are likely to not pull any punches. So if you're looking for coddling or gentle encouragement, you may not find what you seek. If you can take a mixture of honest criticism and callous abuse, possibly tempered with enthusiastic encouragement, you may be in the right place. You can be assured that the voters will not hesitate to tell you what's wrong with your story, and that is sometimes worth more than all the writer's support groups put together. You can also be sure that if your story gets posted, it's probably pretty good.
I know there are authors out there who can spin a good yarn, but just aren't that interested in fighting for a spot in the miniscule short fiction publishing market. Maybe you've written something that's just too odd to sell; something offbeat that doesn't fit clearly enough into any particular genre to get a publisher interested. Send us your huddled stories yearning to breathe free.
If you've got a story to tell, we have an audience who will give it a shot.
