Even if your site is just for reading, have you considered all the above groups?
* Can someone who can't use a mouse navigate your site? How about if they can't use a keyboard?
* Can your default styles be over-ridden? Does it grow gracefully, or is content suddenly hidden?
* Have you checked your color contrasts for the color blind?
* Are ads constantly looping animations?
* What fonts are you using?
* Does it have a consistant navigation?
* What about the content? Is there any attempt to make it as readable as possible? Or are the authors long-winded?
* Is text broken up into reasonably sized paragraphs? Are sections effectively used?
* Is there abuse of all-caps or italics?
Those are just off the top of my head. If you think that the blind and visually impaired are all you have to worry about, you'd be wrong.
