Thanks to wiseguy I discovered a great resource for media anthropology:

Since 2004 the European Association of Social Anthropologists (EASA) Media Anthropology Network is discussing working papers about socio-cultural aspects of media technology uses within the scope of e-seminars via the Network’s mailing list.

… The website of the Network also provides annotated bibliographies, information about media anthropology events, and selected discussions from the mailing list as PDF documents.

They even have an RSS feed.
