Google has a very handy tool called Google Alerts. I've used them for years to track the job market, what's being said about me, Job-Hunt.org, and other things and issues that I want to track, and many other things. Can be overwhelming, but usually they are just very useful.
They are easy to set up and easy to manage. For information on how to set them up and use them, see the article I just completed about using Google Alerts on Job-Hunt.
Happy New Year!
