Filling The Void is a book about how the cultures & psychology of social media use fit within a broader landscape of life under capitalism It argues that social media use is often a psychological response to the need for pleasure & comfort that results from the stresses of life under postmodern capitalism rather than being a driver of new behaviours as newer technologies are often said to be Both the explosive growth of social media & the corresponding reconfiguration of the web from an information-based platform into an entertainment-based one are far more easily explained in terms of the subjective psychological experience of their users as capitalist subjects seeking 'depressive hedonia ' the book argues Filling the Void also interrogates the role of social media networks designed for private commercial gain as part of a de-facto public sphere Both the decreasing subjective importance of factual media & the ways in which the content of the timeline are quietly manipulated--often using labour in the developing world & secret algorithms--have potentially serious implications for the capacity of social media users to query or challenge the seeming reality offered by the established hegemonic order
