Authors need to understand the process by which their manuscript will be evaluated and take that into account when they submit. If a smart recent college graduate can’t decode what your book is about, you’re in trouble.
When I graduated from college I hoped to land a job working on a dude ranch in Wyoming. Instead, I fell into a career in scholarly publishing, acquiring books for Oxford University Presses. I realize now that as an editor I didn’t pay nearly enough attention to the prose. I cared more about the ideas than about how well they were expressed, at least that’s what I told myself. It wasn’t true.
