For what it's worth I managed to read most of the unreadable article. As much as I could justify setting time aside for anyway. For some people it will strike a chord, others not. The topic is timely for me. I might go to a party, but host one? And while I'm content to join a group of people for lunch or happy hour, I'm almost never the one who suggests it or the one who will make the arrangements. I'm far from a complete social klutz, but I find many social situations tiring and I'm more likely to avoid social interaction than go out of my way to create it.
At various times in my life it becomes apparent how much of a liability that habit is.
While nothing in the article itself nor what she likely teaches is rocket science, many people in technical careers (and others) can benefit from really working on their social skills. We often downplay the importance of it and we do so at our own risk. For me it's kind of like running. We all know how to do it, but some of us can only do it short bursts while others can seem to run forever. The vast majority of us can run longer, farther, and faster with training, - and especially with coaching.
Case in point for the IT people. I fought for quite awhile to get IT a spot at the table when major decisions are being made in this organization about what sorts of projects to pursue. What I failed to adequately recognize is that being at the table isn't enough. I need to be actively engaged. I need to make my presence felt and not just be an observer who only speaks when spoken to.
