Apply journalistic principles
One of the best practices of plain writing that will benefit all users is to explain things in a journalistic style. What does this mean? If you compare a book chapter and a newspaper article, you will instantly spot some differences. The most common characteristics of a journalistic style include noticeable headlines and short, simple sentences and paragraphs that quickly get to the point and explain the idea.
This practice makes the text look more digestible and easy to read, especially for people who mostly speak sign language and consider English their second language.
