Well there's our difficulty communicating. I'm talking about all web sites, not just applications that happen to be run in a browser. A regular HTML page with text in it is far more accessible than any application depending on execution could ever be. Web applications can, in very rare cases be made accessible (assuming you have perfect execution and JS feature support in the browser). But actual web pages always are. 99% of the time if you can do it with just HTML and text/images you should.
