To Share or Not to Share?

This chapter deals with the path leading consumers to adopt and use SE, casting light on the drivers and barriers that characterize their experiences. In examining the area of studies on SE drivers, the chapter presents a framework to classify the different motivations, as well as the preconditions and the enablers supporting SE adoption. Trust issues are also covered in this chapter, being a critical element that strongly impacts on SE usage, since exchanges take place both online and often among peers. The ways a platform copes with this issue are highlighted, also through an analysis of Vinted. Different types of SE consumers are described by turning to contributions which identify target profiles. This also helps understand the features of non-users. Finally, the barriers to SE adoption are presented and classified according to consumer attitudes and behaviour.
