INTERCONNECTION > CONTRIBUTION > COMMUNICATION > GRATIFICATION
The main priority of an individual's desire to join an "online community" is to gain interconnections with other users. In order to connect with the other users, individuals must contribute, whether it be informational or media content. This worthy contribution is a form of communication, one of the strongest aspects of "online interaction". However, one must communicate in order to contribute. Without communication, the bonds of individual connections would be lost. Following the contributions, gratification would develop. Pride in one's self and the community as a whole, will ultimately maintain stability.
The importance of online collaboration is very simple. yes it does exist and there will always be room for it. Without it, people would lose that contribution of communication and interaction. And the internet as we know it (WEB2.0) would cease to exist.
