The most common use of the term â€œsocial objectâ€ refers to shared online resources around which interactions develop and coalesce. Examples could include gifts on Facebook, videos, or what have you. The object sort of serves as a shared object, a focus of attention, an actual digital object, and so on. And the object plays a role in governing or informing interactions; we know what objects mean and what to do with them (give them, comment on them, play them, etc.)
So argues Chan, we need a better description, and he gives it a go.
