"Predominant characteristic of tribes throughout time is the need to share and to communicate ideas, thoughts, observations and views. Digital networks achieve this objective by connecting like-minded members of such new tribes across continents! As the principal players move around the arena, a self-assembled dynamic network structure emerges that no single player can control. Digital networks have taken tribal behaviour to a whole new level of collective consciousness: dynamic self-assembling tribes that come into existence almost instantaneously. Human civilisation has gone from local to national and from national to trans-national tribal behaviour and congregation enabled by digital catalysts.
With the growth of the Internet and with its capacity to communicate any and every idea or thought to anyone on the planet 24/7, we have created the ultimate platform for tribal behaviour. Human beings are social animals and need some form of community. Since the time our ancestors gathered together in caves for protection and food we have formed tribes and exhibit tribal behaviour. As civilisation has advanced our tribes have become more numerous and specific. They have developed into institutions, communities and sovereign nations. Now they are manifest as digital tribes, which can be created instantaneously as self-assembling dynamic networks.
The rise of modern civilisation with its secularism and isolationism has done much to break down the traditional tribal bonds. Social observers underscore our weakening traditional tribal influences, noting that young people's lack of enthusiasm to join community groups today can be translated as a lack of social responsibility. However, the conclusion that young people don't want to participate in tribal behaviour does not hold true. They do! It’s just that the format and structure of 21st century trans-national tribal networks is somewhat different from local community participation. It can be described as social networking at one level and a vigorous digital market for the exchange of ideas at another level."
