This study examines whether interactions between members of communities of practice typically have cognitive or social character. Content analysis of more than 7000 posts, automatic words frequencies analyses as well as interviews with community members demonstrate that the interactions between members of the Israeli Ministry of Social Affairs’ communities of practice, the subject of the present study, emphasize the cognitive rather than social aspects. This emphasis is reflected in the content of posts, the avoidance from discussing personal cases or offering emotional support and more. The findings are particularly interesting given the nature of these communities as a space for social workers whose work requires and is characterized by a high degree of social and emotional interactions.
