I just submitted the 3rd and last part of my short story "PCSS7". It's not a typical story. It is formatted as a letter from a charitable foundation's director to a prospective donor, explaining what the next fundraiser is about. Clearly, it's touched some nerves as I've gotten both '10' scores and '1' scores.
I've received email telling me how awesome it was. I've also gotten email from one reader who took the time to explain why he gave me a '1'. It's not really a story. There's no plot, there's no characters, and it's boring.
I have to admit that he's right, he's right, and that depends upon the reader's interests. If you have an imagination, you can provide your own character. Think of it as one of those reader-participation books where "If you go down the stairs, turn to page 36. If you continue through the door, go to page 31". No, those things have no 'plot', either. You're supposed to provide the character.
(And I'm really hoping that it will spark someone into writing a story of their own, using the contest as the background. Whoever wants to do that has my permission and best wishes.)
