If you have a LinkedIn account, you already have a potentially awesome job-seeking network. All you need to do is update your account with essentially the same message you used on Facebook. While you're at it, take some time to look through the connections of your connections. You may want to request some entirely new ones that lead you even closer to that new job.
Make sure your LinkedIn info is current, accurate, and relevant to the job you are seeking. And upload a new and improved photo of yourself while you're at it.
