In the article Deafness and the User Experience by Lisa Herrod, issues with Deaf web users are explored. And there are some excellent points for writing for web accessibility:
- Use headings and subheadings.
- Write in a journalistic style: make your point and then explain it.
- Make one point per paragraph.
- Use short line lengths: seven to ten words per line.
- Use plain language whenever possible.
- Use bulleted lists.
- Write with an active voice.
- Avoid unnecessary jargon and slang, which can increase the user’s cognitive load.
- Include a glossary for specialized vocabulary, e.g., medical or legal terminology, and provide definitions in simpler language.
