If you think LinkedIn is a waste of time and something no one uses, think again. For starters, check out this chart:
More and more companies and people are using LinkedIn.
You might counter: I have never heard of anyone getting a job on LinkedIn. To that I say that people are losing jobs to LinkedIn, in that HR and others are using LinkedIn as a screening process. Good use of LinkedIn might not get you a job, but poor use of LinkedIn might lose you a job.
I’d add that lots of recruiters use LinkedIn, more than you think. The better your profile, the better chance you have to get linked in with someone with a new and better job for you.
Lastly, LinkedIn is becoming a longer and better version of a resume. Just like you should have an up to date version of that, you should have an up to date version of your career highlights on LinkedIn.
