Originally given as talk at an AlterConf in Oakland, Coding Like A Girl addresses gender diversity in the tech and gaming industries and is well worth a read.
...I encourage you wear exactly what you want. Be as flamboyant, fancy, frilly, girly as you would like to be. Do it while being a gamer, a programmer, a game designer. Because you are helping to change people’s ideas of what a programmer/gamer/game developer looks like. And you are making the world a more awesome place by being you. - Coding Like A Girl by sailor mercury
