What is interesting about such lists of N writing tips is the total lack of theory of fiction or narration. It like explaining people how to write software by listing formatting rules/code conventions.
I was just viewing at Max Raabe's take on "Oops, I did it again" on YouTube and realized that the song follows to T all of these writer's advice to, "Keep it short and to the point." In just a few repeated sentences, she manages to dramatize a relatable scene of romantic misunderstanding, while characterizing both a femme fatale and earnest friend-turned lover. It's really minimal. (Richard Thompson's "2000 years of popular music" spiel includes his awesome cover of the same song.)
Also, regarding theory of fiction / narration -- that is a mixed blessing. You see writing software like Dramatica push a particular theory (based on the hero's journey) -- and only if you find the high level of that theory compelling will you find the software to be maximally useful.
Also, I bet the authors managed to avoid a lot of low-tech author / writing community flame wars by avoiding fiction and narration theory ;-)
What percentage of writers in general write according to some such theory? And would their writing improve if they did?
