Abstract
Given the large investments in Enterprise Social Media technologies in organizational settings, this paper sets out to explore the challenges and opportunities that ESM technologies provide for organizational communication. Merging existing conceptual work on ESM with findings from thirteen appreciative interviews with professionals from a large multinational organization, our papers offers six areas of opportunities and challenges -- Social Capital Formation, Boundary Work, Attention Allocation, Social Analytics, Adoption and Use Incentives, and Governance and Control -- that could guide researchers and practitioners in understanding and informing the use of social media technologies in their most productive and impactful ways.
