The current study utilized communication privacy management (CPM) theory to examine how individuals’ blogging privacy management rules are related to their communication-based personality dispositions (self-monitoring skills and concern for enacting socially appropriate interactions). The study also explored relationships between the same dispositions and blogging frequency. Overall, 356 bloggers completed an online survey instrument. Regression analysis provided support for both hypotheses. Bloggers with higher self-monitoring skills had a more private orientation towards their blogging privacy management practices. Bloggers’ CFA level was related to more public and open blogging permeability rules. High self-monitors and high CFA dispositions were positively related to blogging frequency. Implications of the study to current computer-mediated communication (CMC) theory and research are discussed.
