> Because in the real world of web development applications are hardly ever written directly on top of the server. They are written on a framework, that sits on top of an HTTP server abstraction (like Clack), that has pluggable servers.

If you are solving an actual hard problem instead of just driving ad traffic, a framework is going to get in your way.
