When I was working on my book O'Reilly sent me a copy of "On Writing Well" by William Zinsser (http://www.amazon.com/Writing-Well-Classic-Guide-Nonfiction/...). I read the entire book and I thought it was well worth it. One of his best pieces of advice is to end each paragraph leading the reader to the next one; the reader should want to know more.

It's slightly amusing that the first sentence of the linked article is grammatically incorrect: "How to make engineers write concisely with sentences?" is not a question despite the question mark. The second sentence is overly long and uses three commas to give the reader breathing space.
