Some firms use hidden knowledge facilitators (HKFs) to facilitate knowledge sharing among employees within intrafirm online communities. These firms hope for enhanced knowledge sharing outcomes within their organizations without letting employees know that HKFs exist. Yet, the extent to which HKFs’ interventions are effective remains unknown to researchers and managers. Built on the knowledge sharing (KS) literature, this study explores the unique roles of HKFs as moderators between a company and its employees. We develop several hypotheses to test the impact of the quantity and quality of HKFs’ online interventions on several KS outcomes. By analyzing log data of a Chinese corporation's online R&D community, we find that (1) the quantity of HKFs’ intervention has a mostly positive impact on KS outcomes; (2) the quality of HKFs’ intervention has a mixed impact on several KS outcomes, depending on which aspect of quantity is considered; and (3) the quality of HKFs’ intervention also moderates the positive impact of the quantity of HKFs’ intervention in different ways on different intended KS outcomes. This study makes a clear contribution to the literature on knowledge sharing and knowledge facilitation by demonstrating the impact of HKFs on KS outcomes in a Chinese context.

How does the technological infrastructure of a communications medium influence the culture of an online community? Taking up a socio-technical (STS) approach to online communities and computer mediated communication, this study introduces and explores the communication culture of Bulletin Board Systems (BBS) active in Turkey between 1995 and 1996. In the first part of the study, the researcher provides a brief history of BBS networks worldwide and of pre-Internet communication networks in Turkey. In the second part, using a sample from a privately owned archive of correspondences from Hitnet, a national-scale FidoNet-style BBS network popular in Turkey between 1992 and 1996, the study documents how some of the technical constraints on the level of hardware, software, and human-computer interaction (HCI) influenced the communication culture of the Hitnet community. At the same time, the study pays especial attention to the workarounds devised by community members to work around these constraints.
