“…Social networks have proven to be influential in engaging others in political action and deliberation (Biddix & Park, 2008;Gruzd & Roy, 2014), and they have revealed useful insights into the operation of online communities (Gruzd, 2014). For example, by studying underlying social network properties and typology, one can determine whether it is a successful online community or not (Gruzd & Haythornthwaite, 2013;Gruzd & Sedo, 2012), who are the influential members of a group (Aral & Walker, 2012;Gruzd & Wellman, 2014), how information spreads among group members (Bakshy, Rosenn, Marlow, & Adamic, 2012;Grabowicz, Ramasco, Moro, Pujol, & Eguiluz, 2012), and whether there are any densely connected subgroups formed within a group, potentially representing different interests, affiliations, or geography (Ferrara, 2012;Gruzd, Black, Le, & Amos, 2012;Gruzd, Wellman, & Takhteyev, 2011;Takhteyev, Gruzd, & Wellman, 2012).…”
