Serial activists: Political Twitter beyond influentials and the twittertariat

“…These hashtags were popular among prolific users, particularly those tweeting hashtags associated with the Occupy movement, Kony2012, and the Spanish Indignados protests, a first pointer to their character as transnationally followed events. Bastos et al (2013b) also reported that message replication with protest hashtags was not correlated with network topology, with retweets cascading mostly from users with an average following that posted protest hashtags profusely. Instead of depending on user-hubs acting as gatekeepers, message cascades were associated with the intense activity of individuals with relatively few connections.…”

Periodismo en Twitter. La contribución de los usuarios al flujo informativo

“…Parece que en ambos contextos enlazan por imitación, en el sentido de copiar los mismos titulares que proponen los medios, sin seguir ninguna estrategia. Esta realidad se aleja de las investigaciones que sostienen que los usuarios adoptan funciones similares a las del periodista gatekeeper (Bastos et al, 2013;Shoemaker & Vos, 2009), y que contribuyen a evaluar los asuntos de interés (Bruns, 2005;Bruns & Burgess, 2012).…”

“…Para ello, se abordan dos casos de actualidad relevantes en España, #ArdeValencia (incendios forestales de Valencia) y #25N (elecciones al Parlamento de Cataluña), concretamente para analizar los links incorporados junto a los dos hashtags.

También se revisan las fuentes de los enlaces, para verificar si predominan las convencionales y si se introduce a nuevos actores.…”

FCJ-194 From #RaceFail to #Ferguson: The Digital Intimacies of Race-Activist Hashtag Publics

“…Much has been written about the news potential of blogs and microblogs (see for example Siles, 2011;Papacharissi and Oliveira, 2012;Bastos et al, 2013), as well as about the political potential of online space in general (e.g., Bohman, 2004;DeLuca and Peeples, 2002;Downey and Fenton, 2003). In fact, since the dawn of the Internet age, discussion of the democratic potential of Internet-mediated space has been one of the major top level conversations.…”
