"Documentistas would have it so. I can’t possibly build anything for the web without every piece of it being addressable like a document. Users must be able to deep-link into any docu state of my application. These URLs must return content to robots too – because where would we be without web crawlers? – and of course it all needs to degrade nicely for legacy browsers and screen readers. In fact, I may as well just fake the whole thing with server-side markup and progressive enhancement anyway. Many do."

Like most people, I imagine, I don't know what to think about URL syntax and client-side routing. I hope Jeremy and co. will sort it out.
