Some people (like my editors and a couple of readers) seem to not like my short chapters. I like 'em when I just want to give a glimpse into activities elsewhere. I had already written the main story and felt that you'd want to see a little of the bad or other guys' tale. Besides, it builds suspense. Who are those guys? What are they up to?
I know that professional writers -- like David Weber or Tom Clancy -- write several thousand words when they want to fill in the 'others' tales. Not me. I have a hard enough time telling one story, let alone 3 or 4 at the same time.
