Social Media- vital for career?

When reading this article about the founder of LinkedIn, Reid Hoffman,  and his new book, this small paragraph is what stood out to me.

The premise is simple: In a world in which job security has become a thing of the past, who you know is more important than it ever has been. And with a host of new online tools to help you establish your identity and connect with people who might further your interests, to remain un-networked is to risk being excluded from the modern working world.

As ever, the simple phrase, “it’s not what you know but who you know” stands true. As the business world develops and relies even more on modern technology make sure you don’t get left behind.
