screen reader use

WebAIM has just published the initial results of its January 2009 survey of people who use screen readers and other forms of assistive technology (AT). Find the WebAIM survey's initial results here.

I have barely looked at this information, but a few points do jump out at me:

This issue cropped up recently (I am not sure if it has been discussed elsewhere or even resolved). If it has please let me know. With the advent of version 6 a couple of my vision impaired friends have told me they find it much more difficult to use blocks in version 6. This has resulted in some of them going back to using version 5.*. This issue concerns the keyboard accessibility of blocks. i believe there has been a move towards a "drag and drop" model with blocks when re-ordering page content.
