In the fifth grade, we were required to write an outline for our research project essay. Imagine my delight when writing the paper was as easy as copying the outline and adding a couple extra words.
That value of formatting into bulleted lists reminds me of the McPhee method of writing, which was shared last year on HN. He manipulates physical note cards to write, and I was manipulating digital ones.
It is also notable that the Feynman lectures (3 volumes) write about all of physics in 1800 pages, using only 2 levels of hierarchical headings: chapters and A-level heads in the text. It also uses the methodology of sentences which then cumulate sequentially into paragraphs, rather than the grunts of bullet points. Undergraduate Caltech physics is very complicated material, but it didn’t require an elaborate hierarchy to organize.
I think about it a lot when reading markdown feature-driven writing or catching myself doing it.
