“…Even though several empirical studies have been carried out on individuals' use of SNS (such as Chen (2013), Chang and Zhu (2011), Kim et al (2010), and Ridings and Gefen (2004)), very limited research has been conducted oin its use by non-profit organizations, such as professional societies. Knowledge sharing is a core process for professional societies' development (Gerken Golay et al, 2014;Kagan et al, 2015;Kind and Evans, 2015), and the use of SNS and social media is becoming very popular in these organizations (Thompson et al, 2008;Rutter and Duncan, 2011).
