Oh, I don't mean it in that sense. Tess's post talks about how capable people are put off or made to feel like outsiders to the tech scene by hostility from people who grew up with technology and have a competitive and overconfident attitude stemming from a sense of entitlement. I made the reference because I think that this particular method of candidate filtering creates an artificial sense of who belongs and who doesn't. That is, using irc with a command-line client is more an indicator that you grew up chatting on irc than it is an indicator that you're a unix programming guru.
