Social Presence, Social Identity and Participation in Online Communities

In an empirical study from 2006, Shen et al. [1] combined two important concepts - social presence and social identity - in order to investigate their effect on community participation. The structural model revealed that social presence is a decisive factor in creating social identity and that the influence of social presence and social identity on participation is bigger than the fulfillment of information needs (one of the primary reasons why people join a community).
