According to this essay, "Social software has two key attributes that could be considered meaningful to educators: Permits communication between groups and individuals [and] Enables the aggregation and sharing of resources." The people working and living in such a community become producers of knowledge and not just sharers of knowledge. "In this sense, social software allows for a certain level of knowledge co-creation that can be drawn from, reflected upon, and further refined." I think this paper would be stronger were it not so rooted in its references. I wish it looked more widely, more generally, and how social networks support learning, and not just an inquiry stance for teachers. It's a bit like investigating how computers would change education is teachers had them... and students didn't.
