Some of us (me for example) write articles and other text for web users. As it turned out, it's a completely different beast. At least I didn't know, may be just suspected.

Therefore when you adapt your writing approach and already written texts you can improve usability by 159%. And there is a good set of articles to do so. Just read them and apply.
