Looking forward to presenting at OSCON 2007 on Accessibility for Web 2.0!
The top-10 lesser-known benefits derived from making your Web 2.0 site accessible are:
1. Accessibility implementation includes semantic correctness 
which translates into better search engine rankings (SEO.)
2. Accessibility implementation includes having good usability which translates into a better user-experience for everyone, regardless of ability!
3. Accessibility implementation includes maintaining XHTML-valid markup which translates into substantially-improved cross-browser compatibility and is less likely to need adjustment in future-browser releases.
4. Accessibility implementation includes utilizing CSS as the sole source of styles which makes re-skinning your web site a breeze.
5. Accessibility implementation includes being sure that your site can be navigated via keyboard, this also makes it easier for mobile users browsing on a cellphone.
6. Accessibility implementation includes being sure that all JavaScript degrades gracefully in less-able browsers; this also benefits users of web-enabled "appliances" like electronic pianos, refrigerators and vehicle GPS systems.
7. Accessibility implementation includes not representing content or functionality solely by color; this also benefits users who are browsing on the diminutive screen of a cellphone, Blackberry or web-enabled wristwatch that may not reproduce contrasting colors with noticeable distinction.
8. Accessibility implementation includes aiding the usage of alternative input-devices that are designed for special-needs. This primarily involves making your links easy to click which also benefits laptop users navigating by trackpoint, touchpad or similar device.
9. Accessibility implementation makes for great public relations. I encourage every company to implement accessibility and then publicize it as a badge of honor!
10. Accessibility implementation can simultaneously improve both your karma and your e-business. Those with special needs will appreciate being able to effortlessly utilize your site and are likely to become loyal customers; this is especially true if your competitors have not yet implemented accessibility.
