The concept of application usability generally
refers to how well a computer application supports the
needs and expectations of users. It is imperative that security
and privacy features on OSNs are usable to enable users protect
their information as needed. Previous findings inform us that there
is generally an under-utilization of privacy and security features of
OSNs. This under-utilization has been attributed to usability-related
issues, an underestimate of the extent of PID (Strater & Lipford,
2008), and pre-established trust of previous associations
(Nagle & Singh, 2009). OSNs, and in particular, Facebook, provide
several options for managing user privacy. However, unless users
are able to change the privacy and security options to the desired
setting, they may unknowingly expose their private information
to the public. Therefore, we expect the following: H3a: An increase
in the level of difficulty to manage privacy controls increases the
likelihood of private information disclosure
