This article ties in nicely with my earlier thoughts on progressive enhancement vs elegant degradation.
While a lot of the driving force behind design on the Web is sexiness, we can’t forget fundamental usability and accessibility. Federal guidelines require government institutions and some federally funded organizations to ensure a certain level of accessibility be baked into their electronic information mediums. I don’t believe that there are federal guidelines for commercial sites, but Target stepped up regardless.
I know Target takes its position in the community very seriously, it would be interesting to see if settling their case starts a greater trend in how corporations review their site’s accessibility and/or taking stock of the Americans with Disabilities Act.
