I was reading a novel today on a Kindle Paperwhite-or "dogfooding" as some would like this habit to be called. Despite the engaging content, I kept getting jarred out of the ebook by its low production quality. The formatting wasn't even so horrible, but small mistakes kept punching me out of my immersive experience.
The problem originated, I am almost certain, from typesetting for print, followed by poor ebook QA after the conversion was made. It's an issue that's stubbornly pervasive in the industry, and there are a handful of straightforward ways to avoid it.
