I don’t mean to start a fight here, but I think the tech industry, and open source in particular, is snobby. Geek culture is so deeply insinuated into every part of this industry it forms a barrier of entry to everybody already not inducted by a nearly life-long process of immersion. Just like any culture, there are acceptable and unacceptable ways to dress, shows to watch, books to read, hobbies to engage in, and modes of communication.
