People who are high in openness tend to be creative, intellectual,
and curious. Openness is positively associated with frequency
of social media use (Correa et al., 2010), and with using Facebook
for finding and disseminating information, but not for socializing
(Hughes et al., 2012). We therefore predicted that openness would
be positively associated with updating about intellectual topics,
and that this association would be mediated by the use of
Facebook for sharing information (Hypothesis 3)
