“…To do this, we gathered all the Catalan parliamentarians' relations-following/follower (4,516), retweets (6,045) and mentions (19,507)-in the period from January 1, 2013 to March 31, 2014. We decided to analyze these three networks due to the fact that politicians strategically use these layers of interaction in different ways (Grant, Moon, & Grant, 2010;Xu, Sang, Blasiola, & Park, 2014;Yoon & Park, 2012). We have chosen the Catalan Parliament because 85% of its members have Twitter accounts, so there is enough variation to ascertain the rise of new opinion leaders.…”
