Progressive enhancement and accessibility redux - QuirksBlog
This is a really interesting take on the intersection between accessibility and progressive enhancement (which I always felt was there, but this expresses it well):
Accessibility aims to optimize an experience across a spectrum of user capabilities. Progressive enhancement aims to optimize an experience across a spectrum of user agent capabilities.
Indeed, if you broaden the definition of “user agent” to include a user’s physiology, I think the concepts become nearly identical.
