The things existing in cyberspace, physical space, social space, and thinking space (CPSTs) are connected through relationships and interactions. The SocialNet, a ubiquitous network containing these relationships, is getting complex as a result of the interaction between social space and other spaces. Social space plays an important role in promoting the connection and convergence of the other three spaces. While the Internet of Things is described from the cyber view, this article puts forward the concept of SocialNet of Things (SoT) from the social view. The evolution of SoT is determined by the social attributes of things and the changes of SocialNet expounded from the perspectives of philosophy, science, and technology. The case of fighting against the COVID-19 pandemic is explored to explain and support the applicability of SoT. Finally, this article discusses the challenges facing SoT and its future development direction, and illustrates the pivotal role of social space through the generalized social relationships of things.
