Our short-paper on "Lurking as Personal Trait or Situational Disposition? Lurking and Contributing in Enterprise Social Media" is accepted for CSCW 2012.  Here is the abstract:

We examine patterns of participation by employees who are members of multiple online communities in an enterprise communities service. Our analysis focuses on statistical patterns of contributing vs. “lurking.” The majority of contributors (in one or more communities) were also lurkers (in one or more other communities). These results argue against hypotheses derived from common theories of participation and lurking. We propose that contributing and lurking are partially dependent on a trait (a person’s overall engagement), modified by the individual’s disposition toward a particular topic, work task or social group. Contributions include critique of theory, an analytic framework, and implications for design of community services.

The reviewing process for this short-paper was wonderful.  Comments by the Associate Chair and the Reviewers improved not only the text of the paper, but the ideas behind the text.  Many thanks to them, and to the CSCW committee.
