The format of presentation is highly dependent on the content and intended audience. There are many pieces of writing that I would consider broken with addition of outlines and tables; in other cases adding more visual clues for the reader is of course a good thing to do. There is a reason, however, why those alternative to paragraphs forms of presentation are not used widely and that's just because using them properly is hard, and misusing them makes text even less readable. Many people have problems counting parenthesis in their writing, or - more generally - they can't insert an aside into a paragraph (like 'more generally' before or the content in parens here - I'm not sure about the term in English). Heck, many people are incapable of correctly using punctuation and the mess of commas, periods and words they create is completely unreadable. I can only guess, but I think a percentage of people that would create meaningless tables and misleading outlines would be even greater. I'm not saying that we shouldn't encourage more visually appealing ways of writing, but I get the feeling that this should not be a primary concern when so many people are functionally illiterate... On the other hand, maybe - if they are going to loose the ability to read anyway - using tables would be a good, gentle transition back to using ideograms exclusively?
