As an introvert, I'm skeptical of the conclusions of this article. Sales will always include a huge amount of customer interaction, and someone who gains energy from these interactions will always have an advantage over someone who finds these interactions tiring. If anything, I've seen a greater separation of responsibilities, where sales people are supported by technical presales folks who can do a lot of the behind the scenes work.
