Except that not all organic writing-by-numbers is stream-of-consciousness spew. For some writers, an outline is useless because the plot takes on a life of its own, and to stick with the outline would be creative suicide.

Especially since completely plotting it out and sticking to it, no matter how it twists in your mind, can completely destroy the creative process for those involved. It just doesn't work for some people, and that hardly makes them bad writers.
