As of September 2, Panel Picker voting is closed. You can, however, still leave comments on the proposals you find interesting. We will announce the first set of accepted panels on Thursday, October 2. Stay tuned to the SXSW Interactive Festival website for these announcements, or e-mail us if you have questions.
Accessible Rich Internet Applications (ARIA) is a W3C standard already supported by Firefox 1.5+, Opera 9.5, Internet Explorer 8 and Safari. Since its first proposal we built quite a few test cases and examples, and actually implemented ARIA in large corporate websites. Hear about our experiences.
