>>What is the cost to benefit ratio?

This question is irrelevant to ADA compliance. The cost of having wheelchair-accessible entrances, aisles, restrooms, etc. has nothing to do with costs and benefits. It's not a business decision driven by economics, it's a question of complying with the law (and, perhaps, doing one's civic duty).

Happily for web designers, the costs of making a site accessible to the blind are fairly trivial, and are part of good design practice anyway. Why would one NOT apply appropriate ALT attributes, for example?
