This work intends to investigate some forms of participation of authors, readers and critics in digital media, especially on social network media, as part of the process of gaining visibility, and the consequences of this participation. In order to consider these instances of participation, we will analyze both the theorical concepts related to our inquiry as well as publications that may be found in cyberspace, analyses of social network profiles from YouTube, Instagram, participation in book clubs, among others. The curiosity about an author s life, as proposed by Philp Lejeune, is not a new concept in the area of literature studies. However, nowadays, sometimes we may confuse an author s life with what he/she publishes in his/her social media or mix up the authorship with the person itself. The way that the author presents himself/ herself in cyberspace can be crucial for his/her visibility beyond his work. Authors, however, are not the only actors that we may find in play in cyberspace: along, we may also consider the arising of reader s presence. In the context of reader s presence alongside the author in this environment, we still need to ask ourselves the role of the criticism in these transformations that are a consequence of the emergence of these technologies.
