CMC technology was the means to the end of enhancing human relationships in a rural area where long distances made traditional face-to-face community-building more difficult.
This is another useful aspect of virtual communities which we haven't discussed yet: the fact that in some places face-to-face interaction is difficult enough to impede community building. In some rural areas, people live so far from their neighbors, they cannot expect social interaction on a daily basis. Online communication could allow people in these areas to benefit from idea exchange which they cannot get by visiting a neighbor. However, when the technology could do more harm than good is if it becomes an excuse not to organize any meetings at all. Even if people are far apart, periodically travelling the distance needed to meet up is worth building up a sense of community. In such meetings, many people agree to come together in a central location to make decisions and create based on a common interest. Because getting online on a daily basis is realistic, communication vie the web could be a productive complement to these meetings, allowing people to share follow up questions, ideas, or concerns. A sort of parallel could be drawn with our class, in which we meet twice a week to talk, and during the rest of the time share interesting things or ask questions by posting on slack.
