Article's Premise/Title is Slightly Disjointed...
The article's premise is a little bit confusing to me. I agree that networking and forming connections is essential for ANY industry and being able to work outside the box is definitely going to make you more valuable within your organization. But if you're in IT, studying IT to stay ahead of the curve is not an option: it is mandatory.
IT is one of the toughest industries in which to stay competitive, especially given the increased adoption of cloud-based implementations and such--where IT pros are required to develop skills previously beyond their interest level (EX: Systems Administrators being asked to code). With increased globalization, it's also paramount that we not only continue to develop our technical skills, but also our soft skills and BUSINESS skills. We must remember that IT is here to serve people and not the other way around.
So IMO, it might have been more apt that this article's title refer more to the importance of building connections, since that's what the body seems to talk about.
