Online Communications
Web forums are like use the net discussion groups, except web forums exist only on the web. Currently, web forums are much less inhabited than use the net. Therefore, your messages and online communications stand out on the web forums much more than on the crowded use the net.
In my experience, finding a high-quality web forum is more difficult than finding a high-quality usenet group. Nevertheless, when you do find a high-quality web forum, you will have an easy time getting to know the handful of people who frequent the forum. If you find a good forum, you have a potentially great networking situation.
