We offer a qualitative analysis of on-line safety practices and expectations
in a community setting to look at trust practices that contribute to the
complexity of information behaviors in the use of social media. Staging an encounter
between local families by bringing together grandmothers and granddaughters
at a workshop, we interrogate resulting discussions to understand
how information practices are deployed to perform and interpret social identity.
The analysis reveals the importance of trust practices and in particular, shows
the tension between inward-looking and outward-looking behavior and how different
perspectives on trust influence the manner in which communities work to
protect members and police alternative uses of Facebook. In doing so, we add to
knowledge about on-line safety and trust practices and the roles that families
and tools play in supporting, enforcing and augmenting these practices.
