Got this from another list.  The survey looks for useful information.
WebAIM has a new screen reader user survey available at 
http://webaim.org/projects/screenreadersurvey2/

By completing this survey you will help inform development choices for those 
creating accessible web content. All screen reader users, even those that 
use screen readers only for evaluation and testing, are invited to 
participate.

Our previous survey (http://webaim.org/projects/screenreadersurvey/)
had over 1100 respondents and the data collected provided new, valuable 
insight into screen reader usage and preferences. Please help us by 
distributing the URL to screen reader users and disability groups - we're 
particularly interested in reaching screen reader users who may not be as 
technically savvy or connected as the typical WebAIM audience. Developers, 
evaluators, and other sighted users who use screen readers for evaluation 
and testing are also invited to provide their insights.
