In the article and follow-up interview, the author stated that we live in a world that favors extroverts. I would agree completely for the physical world. (I've been lucky in that pretty much all the people I've been close to have been introverts. As an aside, a high-school classmate of dag29580863's once said that he'd only ever heard D say three words in all of high school. D, in his usual inimitable style, retorted, "Make that six.") But I would argue that the virtual world can be as well suited to introverts as extroverts. Online I can take my time responding, walk away, or sequester myself completely (... at least with most of my friends). It lets me stay connected to friends, but on terms I am more comfortable with -- less intense and more ambient, like the occasional connection one has when working independently but with someone else in the same room.
Are you introverted too? Do you also like the affordances of online communication? Does it also help you extroverts out there feel more connected?
