This article deals with two literary artworks which appropriate tweets: I wish I could be exactly what you are looking for by Jean-Baptiste Michel and Working on my Novel by Cory Arcangel. This article questions the issues of appropriationist practices in art and literature in the digital age. The artworks are also seen as entry points to question the relation of power present in the structuration of the expression of users of social network and that the decontextualization of tweets gives us the opportunity to study. They also allow us to reflect on what we call the “attentional fringe oligopoly” of social networks, a structure that wishes to reflect the distribution of the attentional capital of Internet users.
