And not just visually impaired people. I screw these up all the time
and my vision is fine.
It may also be worth considering that accessibility doesn't just mean 
making a web site accessible to the visually impaired. 

According to the WHO, Globally about 314 million people are visually 
impaired, 45 million of them are blind.


According to the most recent Unesco Institute for Statistics data, there 
are an estimated 774 million illiterate adults in the world.


How many web sites are designed to be accessible the functionally 
illiterate?

 Primarily that it is incorrectly implemented.  However, I've yet to
 see an implementation of recaptcha that is accessible and does not
 needlessly insult users with impaired vision.  Even the one on
 recaptcha.net includes the fully-abled=human insults.


The space shuttle is not wheelchair-accessible.  Is that a reason not to go
to the moon?  Are non-astronauts less than human?  People in foreign
countries who don't speak English are not discriminating against you by not
speaking English.  Fancy restaurants don't have picture menus.  People who
don't have the internet can't query google via snail mail.  Do you consider
yourself more human than people who don't have internet access or don't know
how to read?

Captcha isn't meant as a judgment about whether you happen to have a soul or
something, so there's no need to take it personally.  It's meant to keep the
bots out, period.  It's easy to not understand the importance of that if
you've never had to deal with your site getting spammed.  No business owner
in their right mind wants to exclude potential customers if they don't have
to.

If the site itself is not accessible, maybe it's better they use ReCaptcha
and screen people they're unable to serve out before they even try to sign
up...

Umm... perhaps I missed something, but the last time I checked, the
space shuttle had never been to the moon.

Hey, it's Friday.

If the shuttle's door were the only barrier to wheelchair-bound astronauts, I'd
certainly expect NASA to redesign it.

If your captcha is the only barrier to letting vision-impaired users access
your site, I expect you to redesign it.

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!

These are no silver bullet either since language and comprehension
abilities start coming into play. The reality is that any test
designed to weed out the machines is going to week out a few humans as
well. The trick is to figure out how to minimize that number and then
identify who gets locked out so you can find another way to help them.

 I'm not sure it's ever good a good idea to insult your users, or your

Yer too sensitive. May as well be insulted that rocks are too hard.
Bots are a real threat to services. Once they get out of control,
systems can become overwhelmed, legitimate users get flooded with
garbage, and attacks can get launched which can get your site
blacklisted. Then all your users are hosed. It is easier than most
people think for pretty rotten scenarios to emerge.

 Usually recaptcha is a good example of a robot blocker that is  
 accessible to print-disabled users.

My impairments are quite mild (short-sighted with some contrast/light
problems - the photo on my website is a few years old, before I had to
wear my glasses all the time - oh vanity and laziness; and hearing
problems in one ear) but still recaptcha is a pain in the eye.  Maybe
it's worse for impaired users, than print-disabled ones like you?

 The notion that javascript cannot  
 be used in an accessible website is obsolete (it's not 2000 any more).  
 There are javascript techniques that make sites inaccessible, just as  
 there are html techniques that make the site accessible. There are  
 javascript techniques that INCREASE accessibility.

Of course there are, but surely even the most enthusiastic javascript
advocate accepts that the sites using javascript in ways that harm
accessibility far outweigh the numbers using it well today?  So, it's
reasonable if script execution permission defaults to denied and is
enabled site-by-site for now.

However, I wasn't complaining about the javascript use, just noting
that you might find it easier to start seeing the check you're a
human nastiness by switching javascript off.  View Source might
work just as well, depending on how it has been implemented.

 I've recently been learning about accessibility issues [...]

Thank you.  I wish everyone did.  I've been learning about
accessibility issues since my eyesight started to deteriorate and my
hearing was damaged.  This isn't an add-on issue for me.  It's vital
for web use.
