I would venture a guess that the vast majority of "Weird Nerds" are not Katalin Karikós, and instead are simply difficult jerks who are not nearly as smart as they think they are. Hubris mixed with obstinance is a recipe for misanthropy.
Also, the notion that the internet is a place where your outputs are judged solely on their merits, so that you don't have the "ability to sell yourself and your work", is absolutely hysterical.
