Developing technologies that support collaboration requires understanding how knowledge and expertise are shared and distributed among communuity members. We explore two forms of knowledge distribution structures, coordination and cooperation, that are central to successful collaboration. We propose a novel method for  detecting the coordination of strategic communication among members of political communities.

Do formal deliberative  events influence larger patterns of political discussion and public opinion? Critics argue that only a tiny number of people can participate in any given gathering and that deliberation may not remedy - and may in fact exacerbate inequalities. We assess these criticisms with an experimental design merging a formal deliberative session with data on participants' social networks.
