Andy Oram has suggested what looks like a very promising effort: The Public Sphere Guide.
From their website: Facilitating and advancing the study of the transformations of the public sphere to enable its renewal – this is the purpose of this Public Sphere Guide, seeking to create a map of this fragmented interdisciplinary field of study. Co-sponsored by NYU’s Institute for Public Knowledge, this beta version is intended to expand incrementally over time. The Public Sphere Guide serves as a research guide and as a teaching guide as well as a resource for the renewal of the public sphere. At the same time, it also serves as a guide to the SSRC’s public sphere program area. The guide is linked to and receives input from the online essay forum Transformations of the Public Sphere. For more information, see the About page.
