Re: Example of accessible CAPTCHAS that work well

Denis,

Personally, I have sat on the fence between technology, privacy,
security and usability for a couple decades. I believe that when
discussing accessibility (A11y) we need to be inclusive.  If we are
saying that Captchas are not usable that is one thing. There are
plenty of things that are not usable. If we are discussing if captchas
can be made accessible than the answer has to be yes.

The W3C Accessibility Initiatives should not be in the business of
promoting or excluding individual technologies because they do not
approve of their usability or features, in fact if the W3C wants a
broader acceptance for their efforts they should help all technologies
be accessible a great example would be ARIA. In the end captchas like
them em or not can be made accessible and do serve a purpose isn't the
rest simply opinion.

I believe if the W3C started looking at things this way there would be
a wider buy in amongst engineers. In the end the best document will be
the inclusive document IMHO.

Cheers,
Rob Yonaitis
