Sociological analysis of up-to-date social practices, communication and interaction forms among community members, local and virtual groups is based on a number of methodological approaches that need to be reconceived today in connection with the digital transformations of social processes and structures. Socio-managerial approaches used in the era of traditional and modern society (modernity) do not cover the total social reality and do not reply to the tasks and social practices of the post-modern information society (“meta-modernity”). In these conditions, the rethinking is required for the implementation of the basic concepts such as democratic instruments of state regulation, once rejected by Plato and Aristotle and then again proposed at a new round of social development by K. Popper. The concept of participation, which returned to sociological, socio-anthropological and socio-economic discourse in the middle of the twentieth century, needs to be developed in the era of total digitalization, additionally accelerated by measures of social isolation in connection with the pandemic (the transition to remote work, the expansion of online services, etc.). The article attempts to present new aspects of the concept of participation in relation to understanding the models of distributed networks of economic relations (sharing) and, in general, to digital forms of social communications in society.
