I try to keep out of these sort of conversations, or all conflicts in general. But as a fellow writer I feel it is my duty to help out here.
The state of stories in the 'Your Creations' forums is horrid, I think we all agree on that. But I also agree that sometimes people are too harsh. Sure, if a story is really bad it is bad.
Bad spelling, bad grammer and a bad plot. It sounds like it was written by a 6 year old. Children's story books are written better.
This does not mean people have to post saying:
'This story is bad, it has no creativity whatsoever and almost every word is spelt wrong. Grammer is so poor I want to throw up and it is a rip off of another story I have read. Stop writing this now.'
I have seen stuff like that. If a story is bad, do what I do. Don't post on it. If no one posts in a thread the writer will eventually get bored and just stop. That has nearly happened to me a few times with my story (although I hope it is not as bad as some of the aforementioned ones). By posting you bring their bad story to the top of the list of threads and makes it more visible, while good stories get bumped down. If you don't post the story will not get bumped up and will be forgotten (hopefully). If you only post on threads that contain good stories, then the people who own those stories will be encouraged to keep writing while bad writers will be discouraged without even saying a word.
Just a suggestion. I'll probably disappear from this conversation for a while now, as I said earlier I prefer to steer away from these sorts of topics. They never end well for anyone (in my experience anyway).
