It is in man’s nature to form communities, and it is also in his nature to communicate. Psychologists hold that man is moved by instincts, desires which can only find full satisfaction in a community and by communication. Social networking (or network theory) is not an exact science and may reasonably be termed a social catalyst in discovering the method in which problems are solved; organisations are run to the degree in which individuals succeed in achieving goals (Freeman, 2004). In the network theory, social relationships are discussed in terms of nodes and ties: the former individual actors, the latter, relationships within networks frequently described diagrammatically where the node is a point, and the ties, lines of social connectivity (Scott, 2000). Such social network diagrams can be used to measure the social capital of individual nodes/actors: a measurement, or determination of the usefulness of the network to the actors individually, as it is that measurement of usefulness to the individual which not only assesses the social capital of actors, but which by extension may shape and expose the very nature of the network as an entity. Loose connections (weak ties) reflect the greater possibility of openness in the network (Granovetter, 2003). This, in turn, is more likely to bring new ideas, new opportunities, and greater scope for innovation than close networks with many redundant ties. It is clear that “the friendly network” composed of friends already have common knowledge, common interests, and common opportunities. Better still, it has access to wider social geographies. Again, the group with links to many networks has potentially greater access to other social arenas and a more extensive field of information, and thus the individuals, have links to a diversity of networks, as opposed to those within a single network, and can exercise more power and exact more influence by acting as brokers between their own and other networks not directly linked. This “polylinkage,” or “filling social holes,” places greater emphasis on the qualities or attributes of individuals. The ability of individuals to influence their success depends largely on the nature and structure of their network. Figure 1 illustrates a social network.
