Haha, that might have been a bit of a generalisation. Unless the person is socially inept (which, to be fair, isn't uncommon in this industry), I think you eventually realise that nobody is interested in what you are interested in. I just talk about my other interests now, unless I want someone to go away.
Though that in itself is a useful skill at parties:
Scenario 1: Talk about computers, person gets bored and goes away. Success! You avoided having to talk to people.
Scenario 2: Talk about computers, person is really excited to talk about computers. Success! You found a fellow dork.
Wait, when did techies learn to do that?
