wikimedia -- at least wikipedia -- now demands not only my username and password, but if i misspell one or the other, i must also copy the contents of a visual CAPTCHA test in order to prove i'm a human and to log in. this i cannot do, because i cannot visually process the image i am supposed to copy; in other words, i am blind.
since i cannot copy the contents of the visual CAPTCHA test, due to my lack of sight, there is no way for me to login to wikipedia if i misspell my username or password, for to do so, i must copy the contents of a purely visual image;
this is a SERIOUS problem that needs to be addressed immediately; please consult the World Wide Consortium (W3C) Note, entitled: "Inaccessibility of CAPTCHA: Alternatives to Visual Turing Tests on the Web"
as for real-world examples, google is now adding an audio alternative to the CAPTCHA image, microsoft does as well;
for a specific example, consult:
wikipedia username: GJR
real name: Gregory J. Rosmaita
i also find it EXTREMELY annoying that i can't add keywords such as CAPTCH, image, graphic, accessibility, usability, audio alternative, uni-modal UI, blindness, blind, or uni-modal -- why am i limited to keywords if they don't address the topic i'm addressing
i also could not use the "Depends on field because the tracker won't accept:
misstyping userid or password
neither could i use the "blocks" text-entry field, where i wanted to type: access to my accounts at wikimedia;
this form is a NIGHTMARE for anyone attempting to simply assist in the improvement of wikimedia, let alone use the damn thing
I've got to say, I was under the impression we'd be finding some alternatives to help out blind/partially-sighted people when we introduced CAPTCHAs, and so far, this hasn't happened.
Provisionally I would suggest 1) restricting the CAPTCHA to bots and sysops, and/or 2) not introducing it until perhaps three tries instead of one.
(As for the Bugzilla form, it sucks a bit, but it's from before those fancy Web 2.0 user-provided keywords, so you get a limited choice; and "Blocks" and "Depends on" require bug numbers, otherwise they're not much more use than just entering the info in the bug itself.)

there is currently a discussion of CAPTCHA best-practices and alternatives being conducted on the World Wide Web Consortium's wai-xtech public mailing list:
please check out what has transpired on wai-xtech over the past 2 months, and which continues, with participation from the reCAPTCHA project from CMU, representatives of other major implementors of CAPTCHA-type challanges, and please, by all means, join in the discussion -- the more minds, the better, and the collaborative nature of the discussion and attempts to build a better bot-trap mirrors the ethos of wikimedia.
