Writing as briefly and clearly as possible is best for teaching and explaining.
My mouth feels better so I could write a long article, but three, unrelated recent comments have reminded me how much most people appreciate a short and direct message. Unitarian Universalists, as Protestants, make a value of heaping up words, but to what end? As alternatives, there’s the BLUF model, and the inverted pyramid, of course.
It takes time and effort to write briefly, but it respects your readers, who then benefit from quicker, clearer understanding. Your reputation as a truth-teller grows, too. How many word salads add nothing but frustration and papers to the trash? Additionally, this plain language guide has helped me limit jargon, and this typography guide (I cited it yesterday, too) helps make printed works more enticing to read.
