This paper is the result of eight years of work on the concept of editorialization that was done in the context of the international seminar “Écritures numériques et éditorialisation”, which I have been co-organizing with Nicolas Sauret since 2008. I propose a definition of editorialization as the set of dynamics that produce and structure digital space. These dynamics can be understood as the interactions of individual and collective actions within a particular digital environment. Starting from this definition I try to describe how authority works in digital space.
