One of the most successful uses of the Internet has been the emergence of informal knowledge communities or a community of interest. It is an environment usually outside of conventional organizational structures, where people can converse with each other about the common problems they face in their workplace or in their professional life, a common passion for some subject or a common mission. Most communities of practice are contained within a single organization but sometimes they cross institutional boundaries.
A community of practice does not necessarily have to be transacted solely on the Internet and in fact the most successful ones almost always have a face-to-face meeting component to them. As good a tool as the Internet is, it can never replace the intimacy and fullness of communication of face-to-face meetings of individuals. The importance of the internet to a community of practice js that it provides a link beyond the times when people can physically meet and hence sustains the group. It also permits a community of practice to develop among people who are not co-located.
