As a developer, can you weigh in on why you think it might be hard for small businesses to make their web sites accessible? Are there inherent technical challenges that make it difficult to make accessible websites? Or is it that there's a constant churn of new front-end technologies that typically treat accessibility as an afterthought, and typically leave accessibility as an afterthought that will finally get properly nailed down just in time for the next new technology to come along? Or is it business problems such as the client demanding some overdesigned user experience that can only be accomplished by manually implementing non-standard input elements?
