*Because I'm really tired seeing more and more ignorant and illiterate "writers" trying to do something not only without understanding basic rules of storytellling*
Don't have to know the basic rules of storytellling to write a good and interesting story. I don't understand idiots who look more at grammar and other crap instead of the content of the game itself. Besides, every writer has their own style.
You learn from mistakes, how else can you start creating something if you don't try?
