Proceedings of the companion publication of the 17th ACM conference on Computer supported cooperative work & social computing

We warmly welcome you to Baltimore, Maryland, USA, for the 2014 ACM Conference on Computer Supported Cooperative Work and Social Computing! In keeping with previous years, CSCW 2014 presents premier research on computer-mediated collaboration, social computing, and social media, from the design of technical systems for collaboration to ethnographic studies of use in the wild. The mission of the conference is to share the novel research that will advance the state of our art. The conference program embraces a variety of perspectives, reflecting how collaboration permeates different aspects of people's work, social, and civic lives. This diversity of perspectives is mirrored by geographic diversity among contributors. The CSCW 2014 program retains the richly articulated structure of previous conferences in this series including a robust program of workshops, papers, panels, demonstrations, videos, and interactive posters. This year, we also introduce CSCWhat's Next, a selection of forward-looking research-in-progress papers intended to foster discussion. Another innovation this year is the option for demos, videos and poster presenters to give short talks about their work immediately preceding Monday night's reception. Special highlights this year include our opening plenary talk, "Making a Difference In and Through Playful Design," by Mary Flanagan of Dartmouth University and our closing plenary, "Next Generation Humanitarian Computing," by Patrick Meier of Qatar Computing Research Institute. We will also present the inaugural CSCW Lasting Impact Award to Jonathan Grudin for his groundbreaking 1988 paper "Why CSCW applications fail: Problems in the design and evaluation of organizational interfaces." Interest in CSCW'14 is as high as ever, including a record number of paper submissions. The welcome message from our technical program chairs highlights the modifications to the review process this year as we continue to optimize our new revise and resubmit system.
