I do not, however, think it fair to characterize this interest as "primarily to those who are visually impaired". Our interest in serving the blind is quite keen, but many here are easily insulted when it is suggested that we make those accommodations at the expense of others with different kinds of disabilities. > Accessibility for me takes on a different connotation; for me, > accessibility means "machine accessible".

On the other hand, unfortunately, it isn't too difficult to find people who are hostile to the idea of accommodations designed for people with disabilities. Some of these folks react to being publicly shamed. Some respond to threats of lawsuits. Some, I would argue, could be swayed by the arguments for validity (forgetting any relation to disability-related accessibility). I think we could do more to reach this last group, and I think this group might, in fact, be at least as large an audience as the other two. I have no evidence for this whatsoever, but I think it is something we should be considering more than we do. Most of here don't care WHY organizations make their sites accessible -- we just care that it gets done! (This practical any-means-to-the-ends attitude makes Kynn's "Selfish Reasons for Accessible Web Authoring" <http://aware.hwg.org/why/selfish.html> one of my favorite resources.) > On the other hand, if you emphasize accessibility over validity, I feel > you are catering more to the technology that we currently have at hand to > deal with human-media, and future attempts to translate the human media > into other languages/media becomes hampered, since it isn't necessarily > structured. > I agree with this too. On the other hand, most organizations seem to have bought into the idea that discriminating against people with disabilities is a bad practice. The Florida election not withstanding, discriminating against machines seems to be largely acceptable. > Unfortunately, we currently don't have many datapoints of media to analyze > the situation with, but I feel it's likely that other forms of > communication (networked neural implants?) will arise and make the term > "accessibility" take on a whole new connotation. > That would be quite interesting! Among other things, it is actually a take on this that provide a strong argument for the importance of textual equivalents for non-readers. A machine-understandable web holds the possibility of being dynamically and automatically reformulated into a version that is accessible to people with severe learning impairments or cognitive disabilities. The current accommodation techniques (for this audience) of using lots of images (and confounding text with images) postpone this possible future.
