People interact in many ways. The Internet is one of these. Cyberspace is a social construction, just as this University is a social construction. So let us consider whether a community can exist in Cyberspace. If we think about the process of community formation, we realise that the process of community formation is communication.
Communication is the process, and interactions are the elements of community formation.
It has been argued that the Internet is not the network of wire and computers, it is the communication and interaction. That is, the relationships. If 'community is people interacting and relating around shared interests, this can happen on-line. A social system is made up of interactions. Any system of interactions has patterns that can be studied.
