> You are delusional if you think having a good LinkedIn doesn't improve your chances of getting hired... Maybe not for every job, but for many of them, surely.

This isn't universal in every market. Business is very insular here and work follows referrals and introductions. You have those and you have work. Without them, Linkedin won't help.

I'm 35yr in IT; I plug into my clients in a way that I learn their processes - inc hiring. Few white collar employers here use Linkedin. I've never worked with one who did.
