I'm not the OP, but you can contact me if you like; my email is in my profile. I'm not totally blind, and I don't use a screen reader exclusively. But I use one a lot when browsing the web. Also, I worked on the Windows accessibility team at Microsoft for three years, and I wrote a Windows screen reader and a talking web browser before that.
Edit: To answer your other question, yes, JAWS is still maintained and widely used, but it's not as dominant as it once was. On Windows, the NVDA open-source screen reader is quite popular, and the built-in Narrator screen reader is on the rise (though of course I'm biased, since I worked on it). iOS with its built-in VoiceOver screen reader is also quite popular among blind people, at least in the US.
