Participate in a newsgroup

Joining a newsgroup is the best way to target on a group of people with common interests. You can learn what they are saying about the subject in general, and what specific things they like or have problems with. You can conduct market research about new products or promotions, and then you can offer helpful information that will enhance your reputation and increase your customer base.

It is important that you get your message across without blatantly promoting yourself. Use a signature at the bottom of each message you post, identifying you, your company or service and online contact information.
