John Siracusa on geekdom:
Geekdom is not a club; it’s a destination, open to anyone who wants to put in the time and effort to travel there. And if someone lacks the opportunity to get there, we geeks should help in any way we can. Take a new friend to a meetup or convention. Donate your old games, movies, comics, and toys. Be welcoming. Sharing your enthusiasm is part of being a geek.
Anyone trying to purposely erect border fences or demanding to see ID upon entry to the land of Geekdom is missing the point. They have no power over you. Ignore them and dive headfirst into the things that interest you. Soak up every experience. Lose yourself in the pursuit of knowledge. When you finally come up for air, you’ll find that the long road to geekdom no longer stretches out before you. No one can deny you entry. You’re already home.
I think this is the most salient part of the essay, and directly addresses the “us vs. them” attitude, or the “no true Scotsman” fallacies any self-identified group falls into. Like anything Siracusa writes, it’s worth reading in its entirety, though.
