Abstract:

Focus on your users, all of them. Learn from mistakes currently made on the Web. If a user can't fill out a form, they can't buy anything from your site. People turned away by unusable sites will probably try a competitor's site. Don't be the site that turned people away. Make your Web site as usable and accessible as possible. It's the business savvy thing to do. It's the right thing to do. If you don't, someone just might force you legally to do it or threaten to sue.
