Casey,

I've had many conversations on the subject of CAPTCHAs with consultants in
our Talking Book division. Like it or not, many webmasters who insist on
using visual CAPTCHAs (often in combination with JavaScript) are turning
away customers. One consultant, who is blind herself and who is NOT
technologically illiterate by any means, has had to have a sighted co-worker
sign up for her for anything Yahoo! related. When I looked at Yahoo!'s code
a while back, they present the CAPTCHA, with a link (encoded as JavaScript
popup) for folks who can't read the CAPTCHA. JAWS, the screen-reader program
we have installed here, just would not recognize that link. (Note: I just
looked again, and they've improved things considerably -- see below for
code). Jim Thatcher, who is a major voice in the accessibility world, has an
article about some of the difficulties posed by CAPTCHA and its ilk:
http://jimthatcher.com/captchas.htm

There are lots of other ways to minimize bot problems that don't (ahem!)
violate the law, for those of us who work for institutions subject to
section 508 and similar rules. There's a very nice (though slightly dated)
article at http://www.w3.org/TR/turingtest/ on the subject. Logic puzzles,
presented as simple text, are the approach we use most commonly, although
Google's apparent ability to solve some of these does have us a little
concerned.

I'm not sure it's ever good a good idea to insult your users, or your
colleagues. I know that I've seen CAPTCHA's with the message that boils down
to "to help us make sure you're really a human, please fill this out." I'm
not disabled, but I am insulted by these messages!
