Before publishing my own work on Create Space, I had never paid attention to this: Some lines have huge spaces between words! Just before a big word stretched it by jumping the line of course... While this exists in all publications, some have very modest amounts, leading me to believe "filler words" are edited in...

Left totally unchecked, the effect can be hugely jarring I find.

The funny part is, except for critical parts, especially in dialogues (those being better minimally altered), the actual reading "flow", beyond the spacing, is often slightly improved by this re-thinking.

This cost me a huge effort to fix this on 700 pages (to a degree I felt acceptable), yet I realize all this work is valid only for my ONE format...

I can't imagine an editor wading in all this, mucking up the intricate balance of my neat, consistent paragraphs...

I had never heard of this editing issue, although in narrow column magazines (mostly) it would often be really obvious. But a hugely stretched line (say 1/4 "air") still seems very uncommon in the broader paragraphs of books. How is it that this is never mentioned among editing woes?
