Currently working on a literature review of Social Capital – obviously a massive area, so will attempt to narrow it down to recent applications in the specific area of learning and web 2.0. Hopefully the volume of literature will not be too overpowering.
Gale helpfully suggested starting with this:
A Bayesian Belief Network Computational Model of Social Capital in Virtual Communities
Bit irritating to discover that a lot of what I was thinking about covering is knocking about already, although the reference list (and the fact that it was published mid 2007) helps.
