This document discusses Jonathon Hutchinson's PhD research on the ABC Pool online community and the role of its Community Manager within the Australian Broadcasting Corporation (ABC). The research aims to understand how the Community Manager coordinates ABC Pool's activities with the ABC's public service values, and the role the ABC plays in developing social capital. It presents models of the Community Manager's core activities, communication approaches, and stakeholders. The research argues this role can be better understood as a "cultural intermediary" who builds social capital through collaborative creative works. The research has potential to distinguish this emerging professional role and provide first-hand insight into how public media organizations are engaging audiences.
