We have broken HTTP. We’ve done it for years in fits and starts, but apps have completely broken it. HTTP was a good specification which we’ve steadily whittled away.

URLs have a purpose. We are very cavalier about that purpose. We don’t use canonicals. We’re sloppy about switching back and forth between HTTP and HTTPs. We don’t bother to logically structure our URLs. We rebuild websites and let all the links break. We don’t appreciate that crawlers are dumb and they need more context than humans.

The author goes on to complain about the misuse of HTTP methods and status codes as if he had never heard of REST APIs. Overall, though, he makes some good points.
