The main hypothesis of this paper is that the activities of Facebook users in the processes of remembrance and mourning may be considered a form of prosumption. The technology evolution and the digitization process have introduced new paradigms that can not be ignored by social scientists. Within this framework the Sns has a function similar to the so called cathedrals of consumption in the material world. From this assumption we will analyze the process of rationalization of communication from one side and the process of de-rationalization of rationality by the other, through the proposition of four interpretatives models of online dead.
