Social Objects and Object Centered Sociality
Object centered sociality describes the phenomenon where links are created not just between people but between people and objects, or around objects. Once these social objects are identified and built into the network structure then a stickier web application is likely to ensue. Social objects can be either physical or virtual but they each need to be represented by a unique URL on the web.
The relevence of “Social Objects” theory to web application developers was explained at a London Geek dinner by Jyri Engeström, founder of Jaiku.
