When writing and testing HTML, it's standard practice to test with multiple browsers and multiple versions of those browsers. It's also pretty standard to look at usage stats for those browsers - how many people are still using IE 4.0 or Netscape 4.7? Such statistics are often unreliable, but they're still worth considering, especially if pulled from your own server logs. What about screen readers? Is there any available information on usage of various screen readers, and specifically on version? Obviously statistics in this case would be difficult to compile, since you can't simply pull the information from server logs. But it would be valuable. As an example: for a particular upcoming project, tagged PDF files are being considered as the primary document format. When discussing the need, if any, for alternative versions, it would be helpful to know how many users of screen readers would be able to read a tagged PDF file, and how many are using software that can't handle that format. Please note: I'm not asking for opinions on the need for alternative versions - this is just an example of one situation in which having statistics would be valuable. Any pointers to any real numbers would be greatly appreciated.
