Lawyers who need to track when a company, Web site, product or name is discussed in Usenet newsgroups have a new tool they can use. NetNews Tracker is a bot that searches newsgroups twice each day for the phrases that you choose, then delivers new hits to you via e-mail. Each hit includes an excerpt and link to the full posting. NetNews Tracker was created by Kevin Savetz as a personal research tool. When colleagues showed an interest in it, Kevin added a Web interface and made it available to the public.
