accessible ajax
For those interested in building accessible web applications, there is an interesting article over on Juicy Studio describing how screen readers cope with ajax applications.
I lot of my development work makes extensive use of javascript and XML, so it is interesting to read detailed descriptions of how screen readers handle such things. It raises some interesting issues. Often we use javascript to update content on the page, but a user of a screen reader must be alerted to the fact that the content has changed. It makes you realise how often we rely upon visual feedback in our applications.
