[Air-L] user generated content, motivation to post

Hi, A Mater student of one of my colleagues is researching about people's motivation to post, to share comments and evaluations about products and services, and about the social function of such activities. His hypothesis is that people augment their reality by being read and listened, that this activity would reinforce their existence as a subjects. He's looking for references and concepts about these questions. I would be grateful if you could help. Thank you very much, All the best  Amparo Lasén Dpto Sociología I Facultad de Ciencias Políticas y Sociología UCM Campus de Somosaguas Pozuelo de Alarcón 28223 0034913942899 alasen@cps.ucm.es
