[/quote]CAPTCHAs lock out people with language, numeracy or eyesight problems more seriously than spammers.[/quote]

I don't see how a question is going to affect those with eyesight problems, it's actually one of the benefits of using a question because its still acessible. Language possibly but if I'm running a English based forum catering to those that do not speak the English language is not on the top of my list of things to do.
