CAPTCHAs are often discouraged just because they complicate things for
human users too - even those who have perfect eye sight...
Just got a thought, how would this sound:
"Lorem ipsum dolor sit amet, consectetuer adipiscing elit. Now please
type the second letter of the third word here:__"
This would work even with screen readers. But then again, how about
dyslexic persons...
Turing tests are getting tricky... computers are now or soon having
capabilities that human users don't always have - how to let such person
in while keeping computers out?
