Nerd culture has been mainstream since <i>The Big Bang Theory</i>; le geek c'est chic. D&D, Comic books, nerdy plastic-framed glasses, etc... are all "having a moment".<p>So is nerd culture dying? No, it's just being sold now, too. Nerds will never die, as witnessed by anyone who has ever played D&D with a "rules lawyer".<p>Nerds, the people, who are--according to my own mushy definition: socially awkward people who obsessively pursue a niche interest/hobby that is outside of the mainstream. If their hobby/interest is in the mainstream, they know all the lore, such that, if there is an argument to be had about some small detail, they will be prepared.<p>Legend has it, they are in their basements right at this very moment, studying, reading, preparing, for that argument about whether or not the DM was right about encumbrance...
