How do you decide which sites are "accessible" and which are not?
[...]Currently we take into account several factors, including a given page's simplicity, how much visual imagery it carries and whether or not it's primary purpose is immediately viable with keyboard navigation.
what I can make out of this:
page simplicity: flash, videos, sound, dhtml ARE NOT simple so they are 'downgraded' - they may even extend this to table based vs table less designs
visual imagery: image heavy sites, maybe even image based navigation, obvious non-use of alt tags are 'penalised'
