Both Congress and the Bush administration have made more accessible Web sites a core mandate of e-government. The law known as Section 508 requires agencies to make information technology, including Web sites, accessible to people with disabilities. It forced many Webmasters to think seriously about Web design and usability for the first time. But talking about usability and making sure it happens are two different things. Usability means more than coming up with a good site design. It requires follow-through, and that's where many agencies — short-staffed and with little time or money for training — often come up short.
