Interesting I have been thinking about the same thing in the past few months. At least for Web Apps.
But I cant read the article on Medium. Why is everyone putting their blog on Medium anyway?
It's no longer an interwoven hyperlinked system of documents, it's not longer the web if this happens: it's just pretty pictures, unscrapable, un-user-scriptable, with arbitrary actions undernearth. There's no rules, no medium here: just animated whatever, pixels blasted in your face, with no structure, no documents, no system underneath. This would never ever be anything like the web.
