Edward M. Grant says, in a comment on The Passive Voice:

Most readers don’t care about ‘quality’ in the English teacher sense. They just want a good story that’s told in a readable manner.

I reply:

Which is to say that they are very picky indeed about actual quality. It’s just that the quality of a story as a story is not the sort of thing that English teachers are well equipped to analyse; so they pick and pick at relatively unimportant details of prose technique.

The trouble with publishing first drafts, for most writers, is that we very seldom get all our best ideas on the first draft. Right now, for instance, I am (shirking) revising the second book in a series that I am bringing out — an important structural revision. I realized a while ago that the pacing wasn’t holding up well in the earlier part of the book; and in the course of figuring out why, I came up with a much better way of getting the plot from point A to point B, in such a way that all the elements of the story would come together at point B with a bang, instead of making little popping noises one by one along the way.

John Cleese talks about how one of his fellow Pythons, though more talented than Cleese as a writer, never wrote scripts as original as Cleese’s. This (said Cleese) is because the colleague would go with the first workable idea he thought of, and knock off at 5:00, whilst Cleese would stay for an extra hour and a quarter, trying different ideas until he came up with something better. A lot of writers do this kind of work in the second draft. They’ve built the skeleton of the story, and have a working route from beginning to end; now they can make structural revisions to come up with the best route.

Readers will never consciously notice that all this work has been done, but they have a very shrewd way of being able to tell when it hasn’t.
