An Interesting and entertaining article.
The most interesting part to me (as someone with vision problems) was the WebAIM link [1]. The biggest problem I have is with the almost total blind adoption of low contrast (so often too low for me to even read) and sure enough the section about low contrast [2] says:

My basic question then is why do so many designers and websites choose to break the WCAG guidelines?
