I agree with Yoron about this not being a professional's writer's website to post their works of art but one for us amateurs to have fun and enjoy.
Adding to his scoring philosophy I submit two points. First, I think someone who posts a ridiculously low score because he wants to boost his own score should be banned from the site. Perhaps that's an impossible thing to do, but I think you get my point. It's not fair.
My other point has to do with serial stories which I tend to write. I just can't hold back posting during time it takes to write a complete novel. I've found many times the reader gives an extremely low score to an early chapter because he just doesn't see it.
I've even had a few "1's" and "2's." Really now. If someone can work out how to post something here, he deserves at least a "3."
But that's not what I'm referring to. What my point here is, if someone gives a serial story a low score early on, they should go back after a few more chapters are added and see if the score was justified. If the story starts to make sense and perhaps the spelling or grammar errors have been corrected, CHANGE YOUR SCORE!!!
Finally, I feel a score say below 5 or 6 should require a comment to at least tell the author what the error of his ways are.
That's the way I see it.
