@AnRoinnUltra --- Thanks for your interesting comments and questions.
First, I'm not sure what you are asking so maybe I'll be answering things you are not asking.
I do not review my own stories. I couldn't be objective about my own story and I would guess that it could be seen as providing more background and information about my story, which would be unfair. --- The same could be said about my commenting on other people's stories but I think there are two mitigating factors. First, commenting positively on other peoples stories has been encouraged from day one in this contest. Second, I did not write the stories I am reviewing and my review only represents what I saw in the story. And, as my wife tells me all time, I can easily be wrong. I expect that everyone is completely aware of that.
When I review, I try to say what I feel is the heart of the story for me and I try to put as positive a spin on it as I can honestly do. If there were a truly dreadful story I might have a problem. But nothing truly dreadful has ever appeared in these challenges. Certainly, there have been stories that I have not understand, and sometimes my review stands to highlight my own denseness.
I've got to admit that in light of some of the comments on the 300 Word discussion I am a little less sure if I am doing a service to this contest or not. What I am completely sure sure of is that In the end how good a story is, is a lot like beauty. It is all in the eye of the beholder. In the Chrons challenges I find a lot to like.
