Benefits of Evaluating Web Sites for Accessibility

For  "[Draft] Evaluating Web Sites for Accessibility" 
[http://www.w3.org/WAI/EO/Drafts/eval/]
I volunteered to draft a short paragraph under the heading:
2. Benefits of Evaluating Web Sites for Accessibility

Here is my first attempt, for discussion:

Evaluating a Web site for accessibility gives a practical path to reaping 
all the benefits – technical, legal, social and economic – that are 
described in detail in
“Developing a Web Accessibility Business Case for Your Organization” 
[http://www.w3.org/WAI/EO/Drafts/bcase/].  An evaluation may highlight 
accessibility problems with a site and learning how and why to fix those 
problems (and then fixing them) will deliver those benefits.
