I have no idea!
I'm going to guess a slight indent at the start of a paragraph OR with little spaces between paragraphs (more than what is normally between the lines but less than the height of a line with text) and more significant spacing between sections.
I also like new sections to start off with a big space before it and three or four words in all capitals -- or some other adaptation of the letters. I do not like the stars or bars or any other divider -- I'd rather the distinction appear in the text itself.
