Whether one is legally obliged to make a site accessible and usable by "all" or not, accessibility and usability is a very interesting and important topic.
W3C has gotten better and better at laying out "best practices" in a way that is applicable to a wider array of sites, and are suggesting quite basic implementations that can be adhered to by most.
In other words -- this is good stuff, and I wish more actually paid attention. Designing a site with usability and accessibility in mind tends to lay a good foundation for avoiding other issues.
