As redes sociais na divulga？？o e forma？？o do sujeito do conhecimento: compartilhamento e produ？？o através da circula？？o de ideias

social networks are virtual environments in which subjects relate to each other by instituting a form of sociability connected to the dissemination and the very construction of knowledge. the sociability in social networks, such as orkut, facebook and twitter does not have the same conditions of production that the sociability in students' spaces such as school or university, for example, because the imaginary that governs these relationships is different from the one that governs the relationships in social networks. in networks, this imaginary is related to a manner of subject's constitution that is passed by the formulation and circulation of a knowledge of the world. that is how the social networks will be discussed here, as object of analysis, in order to understand how the subject of knowledge constitute himself through social networks, as he gives visibility and express, disseminate and produces knowledge.
