Every professional should be on Linkedin. There's no downside to it. Set it and forget it. Or, if you want to get more out of it, share some stories pertinent to your industry, and participate. Connect to as many people as you can -- alum of your college/professional school, or high school for that matter, people at your company and companies you've worked with, etc. It hasn't resulted directly in me getting work -- yet -- but it has resulted in me making and receiving oddball contacts and requests to hook one contact up to another. Those kinds of contacts and favors are what I hope will eventually net something for me too.
