Who has had success with LinkedIn?

I use LinkedIn as a recruiter for my organization, and I utilized it from the job seeker perspective. Not only do you want to build your network, you will want to join "groups". As a job seeker I found the groups had the greatest value. I was looking to relocate to an area where I did not have a network and posted that I was a veteran seeking employment, and the location I was searching. I would receive a number of helpful responses of opportunities, and contact information.
I also recommend any recruiters you come in contact with via job fairs, etc. find them on LinkedIn and connect with them. Send updates to them if you apply for a position, etc.
LinkedIn is a powerful professional tool that can greatly assist you in your transition.

How would you define "success" with LinkedIn SFC Stephen King? I been on LinkedIN since my transition and have found it to be a good tool especially if you take them up on their free Premium account for transitioning Veterans. But, like anything in life, you get out what you put in. I took the time to sit down and polish up my LinkedIN profile and now include on the resume as a way for possible employers to see my skills and what others are saying about it. I've been told a few times that is why I was selected over other candidates.

I'm able to keep in contact with former co-workers and use them as references. I'm not sure if I'd be where I am now if it wasn't for Linkedin
