With Google Alerts you can set up a monitoring system to track anything you want, such as finding out what’s being said about you or your company; keeping track of articles you write under your name; monitoring the competition or simply to keep up to date on any given topic.  Google automatically notifies you when new content from news, web, blogs, video and/or discussion groups matches the search terms you set for it.   This is a free tool.    www.googlealerts.com
