Many years ago, when I was learning about pair programming, I remember someone (possibly even Kent Beck) saying that "Pair programming is kryptonite for incompetent introverts!" and I remember thinking, "Well, yeah, but I bet it's the haven of incompetent extroverts!"

While I haven't really been in forums debating the merits and perils of paired programming, I cannot help but be amused by this essay, that pretty much confirms this initial thought I had about paired programming!
