Whenever writers try to get anything published, they encounter editors. By that time, they should have already been editing it themselves. Writers and editors have a complicated relationship. I’ll share some quotations in a bit. On the bright side, editors will catch that glaring error writers have missed in a dozen sessions of proofreading. That is, of course, in the case of writers who actually proofread before sending something off. I’m thinking of one particularly embarrassing error of fact I notice in print that I wish the editor had noticed earlier. But editors have also found spelling errors and instances where I apparently tried to rewrite a sentence and got distracted, never to notice again. English has weird spelling, but it also generally has one and only one correct spelling of a word. Punctuation, on the other hand, has various principles about which people disagree. Sometimes passionately. If a writer who hates a lot of commas works with an editor who loves to add commas, they might come to blows. Maybe literally.
