Comment Spams Straining Servers Running MT

This has been going on for quite awhile now, and still no official fixes from SixApart?
Shame on them.
Correcting lack of access to text on the Internet is easy: just buy a PC with a screen reader and an account with an ISP. Correcting lack of access to distorted images of text on the Internet, on the other hand, is non-trivial: if the CAPTCHAs are easy enough for blind people's OCR, then they're easy enough for spammers' OCR. If you must use a CAPTCHA, then make it something other than an image. Ask yourself: what questions can a blind person answer that a spambot can't?
Captchas are currently great for weeding out automated spammers; unfortunately, they're also great at weeding out people who cannot see. This unnecessarily renders your site inaccessible to a portion of your audience. From a geekier perspective, this sort of assumption-laden web design runs completely contrary to the accessible, device-independent spirit of the original WWW.
Of course, since the blog you linked doesn't even work at all as I write this, maybe you're not concerned with accessibility for anyone!
