John Scalzi explains who gets to be a geek (spoiler: anybody) and the difference between geeks and hipsters:

Many people believe geekdom is defined by a love of a thing, but I think — and my experience of geekdom bears on this thinking — that the true sign of a geek is a delight in sharing a thing. It’s the major difference between a geek and a hipster, you know: When a hipster sees someone else grooving on the thing they love, their reaction is to say “Oh, crap, now the wrong people like the thing I love.”

Update: John Scalzi have a follow-up here.
