“ If you’re talking about writing, that’s easy; write in English, using proper punctuation, capitalization, etc., and simple words. Tell the whole story in the first sentence of no more than three lines, one sentence per paragraph.
Get to the point quickly; write concisely, in the active voice; avoid redundancies; write in the past tense; attribute properly; when you change speakers, attribute first.
If you’re talking about appearance online, use a sans serif type, 12-point (for ease of reading), write no more than five lines per paragraph and skip a line between paragraphs. No need to indent the first line.
Every four paragraphs, insert a subhead telling what’s coming next.
