A list of what I think are the Top 5 important rules to consider for Writing online:
- Put the focal points of the document in the first sentence/paragraph, a list would be suitable also.
- Try to steer clear of visual distractions.
- Use links that relate to your topic's but try to make sure that those links do not lead your readers away from your page completely.
- Make your sentence's/paragraphs as short as possible whilst still getting to the point, a lot of text can drive users to just simply scan or to go away from your page , BUT remember also if they really want to read your page they will print it out so perhaps add a PDF printout file for them to print out.
- Try not to base your work on providing a massive amount of links, especially to external sites, the net is forever changing and if you have a page with a bunch of dead links your page will then become useless.
