Social objects somehow resonate with the concept of boundary objects discussed in a technology-enhanced learning context.
“Boundary object (BO), originally introduced by Starr (1989), is a concept to refer to objects that serve an interface between different communities of practice. Boundary objects are an entity shared by several different communities but viewed or used differently by each of them. As Star points out, boundary objects in an organization work because they necessarily contain sufficient detail to be understandable by both parties, however, neither party is required to understand the full context of use by the other – boundary objects serve as point of mediation and negotiation around intent. Boundary objects are flexible enough to adapt to local needs and have different distinct identities in different communities, but at the same time robust enough to maintain a common identity across the boundaries to be a place for shared work. Boundary objects are not necessarily physical artifacts such as a map between two people: they can be a set of information, conversations, interests, rules, plans, contracts, or even persons.”
