I am amazed that I had never read the article Caring for Your Introvert  before. One of the interesting points concerned acting like an extrovert (I can do it for the duration of a typical job interview). Another was the issue of recovery time after having to deal with people. When living in hotels (which I did for about 18 months straight in 1999 and 2000) I found that some days I would reach my quota for dealing with people before I had dinner, going to bed hungry seemed like a better option than going to a restaurant.
One thing that occurred to me is the lack of apparent introversion among most delegates at computer conferences. It seems that the majority of people who are any good at coding are introverts and you might expect an environment with a majority of introverts to be somewhat quiet. An interview with the author of the article  published 3 years later explains this (among other things). Here is a quote:
But once an introvert gets on a subject that they know about or care about or that intrigues them intellectually, the opposite often takes hold. They get passionately engaged and turned on by the conversation. But it’s not socializing that’s going on there. It’s learning or teaching or analyzing, which involves, I’m convinced, a whole different part of the brain from the socializing part.
Which describes a lot of the activity at conferences. It’s standard practice for people to walk up and join a conversation that covers an area of technology that interests them and then just walk away when the topic changes.
I wonder if any of the social networking and dating sites have a section for Myers-Briggs  test results.
