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.” When a geek sees someone else grooving on the thing they love, their reaction is to say “ZOMG YOU LOVE WHAT I LOVE COME WITH ME AND LET US LOVE IT TOGETHER.”
Any jerk can love a thing. It’s the sharing that makes geekdom awesome.

It’s why I love tumblr: there’s tons of people here expressing love for something. Sharing their love. And by sharing our love, we deepen it. “Can we talk about this scene?” “Did you notice how…?” “You see what she does here?”
