July seems to be the month for reviews, so I thought I'd organize some of my observations on scientific writing into bite-sized advice posts.
1) If you want to get your paper accepted, please, for the love of all things, use short paragraphs.
I was reviewing a two-column ACM format paper recently, and a few paragraphs took up the entire left-side column and half of the right-side column. My eyes went blurry by the end, and frankly it negatively biased me against the authors.
If authors are concerned about space, they should either use less words or make their diagrams smaller. I'd much rather see smaller diagrams and more readable text than huge diagrams and squished prose.
Also - putting hundreds of lines of code into a paper is rarely necessary. (And XML is never necessary*). Use small chunks. Just the important idea behind the awesome algorithm. If the code paragraphs are taking up more than half a page, please consider an alternate presentation style. (See Justin Zobel for nice presentation ideas).
