This is also one of the most powerful strategies for your job search. The best ways to use the Internet for this purpose are newsgroups, mailing lists, and special interest groups. There are thousands of newsgroups devoted to every topic you can imagine, and some that you probably can't imagine. You may find job listings, job wanted postings, industry news, or career advice. Best of all, you can talk to people in your field.
Mailing lists are less interactive than newsgroups.
Once your name is added to a mailing list, you automatically receive messages posted to the list in your mailbox. Along with the messages, you get the e-mail addresses of everyone who contributed a message. Like a newsgroup, this is a great way to make contacts in your industry, learn about job opportunities, and read up on industry issues. Special interest groups are a more organized version of newsgroups. They exist on services like American Online and Compuserve, and they actually have paid administrators.
