> If you read "ect.", your brain automatically corrects it to "etc." because you're used to seeing it often. It's probably subconscious, right?

Not at all. Seeing errors like "ect", use of the wrong words like the all-too-common mix-up of "then" and "than", and even the omission of dots in things like "eg" and "ie" is very jarring to me. It usually pulls me out of automatic reading in order to consciously work out what the author actually meant. Even when I've worked it out, I find it hard to substitute the real meaning for what's literally there. Not that I necessarily blame the author, as I understand that mistakes do happen, but it does noticably harm readability for me.

I do find your description of your preference on assistive technology very interesting, as it differs from the preferences expressed by my visually impaired friends. They get varyingly amused and annoyed by their screen readers not understanding idiomatic things and reading them too literally. I wonder if the difference is that you're the kind of technical person that reads Hacker News, whereas they're both arty types who don't really do computers any more than the average person does. I suspect that were I to ever need to use a screen reader, I'd prefer the dumb ones like you do.
