As Social Media continues to transform and expand contemporary linguistic landscapes, this paper intends to add to the analyses of the new communicative practices taking place in these sites. Even though social media has been a worldwide phenomenon, Latin American participants have been rather overlooked in the scope of social media studies. Thus, in this research project, I focus on Latin American youth as active interactants of social media discourse. This project displays the preliminary stages of what is currently unfolding as my senior thesis. Through analyzing conversations taking place in popular YouTubers' channels from Bogota, Colombia, this study focuses on disagreement as a positive communicative strategy to build a set of identities (Ardington, 2013). Participants in these communities of practice display skillful communicative competence to successfully demonstrate their identities as followers. Disagreement in these sites have multiple functions, it allows interactants to increaseparticipation, to create connections between participants, and to actively negotiate a different set of identities, thus creating agency.
