DFW is the classic example of prose which is incredibly pleasing to read, but isn't actually better at conveying information. He routinely expands banal topics in philosophy into pages. I don't think his intent was ever to bring the reader up to speed on a topic, or convince the reader of a particular philosophical position though.

Many people try to emulate his style, usually they fail, and if they succeed it works against the purpose of their writing, which for most people, most of the time, is to communicate an idea.
