First off, as I've said elsewhere, I'm not big on plot, from both reader and writer perspective. My greatest inpsirtion and influence for my WiP is HST Fear and Loathing in Las Vegas. I know many consider this to be a record of Gonzo journalism, but for me it's a work of fiction. All that said, I still stop myself when writing a scene - chiefly because of all the damn 'rules' we new writers get thrust down our throat - when I suspect a scene will fizzle out and come to nothing. Would reading such a scene make you stop and ask 'What was the point of that?' or would you accept it as being part of the book's make-up and style? Or, is the mere prospect it's going somewhere enough to justify it? For instance taking the reader into a scene with the potential to lead to a significant event.
