Social capital
Social capital is said to be a multi-dimensional concept, with both public and private facets (Bourdieu 1991). That is, social capital may provide value to both the individual and the group as a whole. Through informal connections that participants build in their community of practice, and in the process of sharing their expertise, learning from others, and participating in the group, members are said to be acquiring social capital – especially those members who demonstrate expertise and experience.
