Amid the widespread diffusion of digital information technologies, the media-

scape is changing in various ways. Perhaps most visibly among these changes, new

configurations involving social actors, technological actants, work-practice activities, and

different kinds of audiences have become interlinked in ways that confound boundaries

between production and consumption, professional and nonprofessional, and intra-

and extra-organizational domains. Thus, the nature of who or what-whether human

actor or nonhuman technological actant-guides message formation and circulation,

and how such media-shaping takes place in relation to whom (certain kinds of audi-

ences) may require some rethinking.
