Just read on Gez Lemon’s site Juicy Studio that with WebKit’s recent announcement of support for WAI-ARIA, all the major browsers are now doing something to support it. This ROCKS!
For those of you not familiar with WAI-ARIA, it’s a World Wide Web Consortium (W3C) standard for making all those ajaxy fancy user-interface components (like tree menus or alerts) accessible to people with disabilities.
Last year at a W3C conference, I got to see WAI-ARIA demoed by a blind gentelmen. It was WAY cool. I hope all browsers move quickly to suppor this as much as possible.
