At one point I got weekly project updates from a team I was working with, and one guy wrote dense, short, emails where I would have to read every sentence carefully to get a hang on what was going on. Another guy would write longer, fluffier emails but with bullet points and paragraphs in the same order:
> Hi everyone!
> {fluff}
> {general status}
>
> - Bullet points of things done that week
> {comment about things done}
>
> - Bullet points of things to do next week
> {comment about potential problems etc}
>
> {fluff}
> {annoyingly long footer}
Just by parsing the number of bulletpoints, and the length of each bullet point (and the first word) I would get a surprisingly good grasp on how things were going, and what was hard/complicated (longer bullet point -> more complex), and very easy to read about exactly I wanted to know.
