I just learned about Google Alerts.

It’s a simple service where you enter keywords for Google to search. Then Google will monitor the search results and send you an email whenever new hits appear in the search result.

Time will tell if it’s truly useful to have your own personal intelligence service at your hands. So far I receive alerts about the company I work for, the region where I live, myself, and so on.

Update, May 29: In my experience there are too many ads at the top of each email I receive. Also, Google sends me a daily email for each alert even though there are no new search results.

Thus, bulking alerts would be a nice option. Or perhaps you could write something better by coding against the Google APIs.
