Accessibility is a very interesting topic and has become near and dear to my heart in recent days. I'm preparing for CSUN, a large accessible technologies conference down in LA in March. Part of this includes ramping up my knowledge about what it means to have an accessible application (ie is the app I'm using accessible) and building accessible applications (ie do my tools make it possible to build accessible apps). With .NET we made a lot of improvements to surface the accessibility infrastructure in Windows and WinForms but on ASP.NET there were some issues. Since those initial releases there has been a lot of discussion and changes made to ASP.NET in order to make building accessible Web applications easier. To do all this learning, I've been working with Sara Ford, who has been instrumental in helping me get up to speed with all of this stuff. I can't even begin to tell you how overwhelming and eye opening it all is.
Sara has a great post about how to test for accessibility -- This should be required reading for every developer. Now I just need to convince her to write this document for Web applications!
Oh T-16 weeks until Tech Ed... geez..
