Yup, that is why I don't hang out with geeks (at least computer ones). Most startup geeks and developers as you refer to them should step away from the keyboard and join a house league sports team; one with people they can talk to that won't whine that the iPad sucks because it only has 256 MB RAM. Most of these geeks should aspire to be as sociable as Richard Feynman was. Not only will it help them achieve their goals, but it will make reaching them all the more fun.
I'm one of those introverts - being around lots of people I don't know can be exhausting for me. But the point is, it has a great payoff, so I still do it.
