Really, how often do you see these things on mainstream sites? Most developers who care about those things are fighting other developers or founders who continue to use the "We need to make money, not be standards compliant" argument.
When I give talks on accessibility, that's the #1 thing people say. THey can't be bothered to care because they believe that time could be better spent solving their business problems. They often truly believe that it's too costly, or that their target audience doesn't care.
And sometimes, they're spot on. Fact is, people come to web sites (not apps, but sites) for content. If it's wrapped in a crappy container, people tend to just deal with it, as long as the content is worth their time.
