Sure, in theory it’s a nice idea – one less draft to plod through with immediate insight into where your manuscript needs help and what you’re already doing that’s working… Now, if you edit as you write (which not many of us do), then this is a more than realistic point of view to have. Essentially, you’ve all ready done a second and maybe even a third draft during the writing of your first draft. However, at least half of all writers go with the “vomit on the page” method to some degree or another which is not conducive to the logic stated above.
