A nerd is first and foremost a consumer. That is what nerd culture is all about: consumption. Brand loyalty. What best represents nerd culture these days? Big Bang Theory. Comic Con. I have never watched an episode of BBT but I know these dorks love their comic book superheroes and other franchises. Nerdom revolves around franchises and brands. Star Wars. Super heroes. The loyalty and obsession with them. These Funko Pop figures. lol. Nerds buy the products. I buy the stocks. In this same vein, people like Mark Zuckerberg and Bill Gates are not nerds. Being smart and being into science or tech or whatever does not make one a nerd, being a mindless consumer does.
