"The best part about being a nerd within a community of nerds is the insularity – it’s cozy, familial, come as you are. In a discussion board on the Web site Slashdot.org about Rushmore, a film with a nerdy teen protagonist, one anonymous participant pinpointed the value of taking part in detail-oriented zealotry:
Geeks tend to be focused on very narrow fields of endeavor. The modern geek has been generally dismissed by society because their passions are viewed as trivial by those people who ‘see the big picture.’ Geeks understand that the big picture is pixilated and their high level of contribution in small areas grows the picture. They don’t need to see what everyone else is doing to make their part better.
Being a nerd, which is to say going to far and caring too much about a subject, is the best way to make friends I know. For me, the spark that turns an acquaintance into a friend has usually been kindled by some shared enthusiasm like detective novels or Ulysses S. Grant.
