Well it's split into 5 basic groups, gamers, anime fans, comic readers, myth studiers, and fantasy writers right?
Those groups are all coexistant somewhat, and the more precise and picky about what you play for games, watch for anime or read for fun.
Ex. A PS2 gamer might make fun of a nintendo gamer b/c of the "kiddyness" in nintendo's style as of late. Both equally geeks, but one geek makes fun of the other. Like a food chain.
That clear things up?
