if I was hiring a business development guy and one guy was connected to all the senior people I wanted to do business with and another guy didn't have a LinkedIn, I would favor the first one. For some things it's an important signal, if not a red flag that someone isn't switched on and plugged in.

If someone wanted to be my social media guy and wasn't on social media/Twitter, that would be a red flag too!

Just like there are jobs where one should probably have a Github or public portfolio, there are jobs where one should be on LinkedIn. It's a tool one should know how to use, not the sum of one's identity.
