I. Introduction
Social computing is more than the identification of multidimensional clusters from usage logs. Parson [16] popularly described the importance of the normative aspects of social organization. Lockwood [15] in turn critiqued this focus on normative social structure, arguing that it is the non-normative or, to use the vernacular of the day, deviant behavior through which systems of social organization evolve. Social computing systems evolve more rapidly than the systems Parsons or Lockwood studied. Social computing represents a form of social experience and a range of new computing capabilities that enable, sustain and constrain social experiences. The phenomenon of rapid change to social structure in social computing contexts calls for the development of new constructs to explicate the nexus of person, task and tools in social computing.
