Rede Social X, Comentadores, DiscussãoResumo
Neste texto questiona-se a existência de discussão e discordância de ideias nas plataformas de média sociais, particularmente na plataforma X. O panorama atual, tão contaminado por desinformação e discursos extremistas (agudizando-se a contestação às Big Tech e o abandono de algumas plataformas digitais), sugere que convoquemos contributos teóricos que remetam para o desencanto com as TIC e para a perda de racionalidade na esfera digital. É na direção desta última que também nos conduzem os resultados da pesquisa que se apresenta, através da qual se pretendeu indagar se quem participa nos programas de debate e comentário político dos canais de televisão também discute, entre si, na rede social X (por ora ainda a mais direcionada para a discussão de temas políticos). Para tal, analisaram-se as publicações das contas de dez utilizadores desta plataforma durante o último quadrimestre de 2023.
