Hehe. It depends a bit on the social group. But most people will be aware of it before I even open my mouth… Dunno, maybe it’s the long hair, or Debian t-shirt or something like that. But I rarely have to (verbally) disclose the fact I’m a nerd 😉 There’s some danger of confusion with the metalheads, but you know, people can fulfill several stereotypes simultaneously, so… confusion avoided…
