Web accessiblity in mind (WebAIM) have published results of their screen reader survey. While reports are often boring, they are often very useful, and this is one of those reports. Screen reader use is often forgotten during the build of a website in the jungle of SEO and the like. The report graphs things like how people browse sites (i.e. whether headings are useful), how often they find skip links and how often other usability good-practices are encountered. Give it a read and improve your web build process.
