David Ellis et al. have self-archived "Changing Styles of Informal Academic Communication in the Age of the Web: Orthodox, Moderate and Heterodox Responses."
Here's an excerpt:
Purpose—The purpose of this paper is to report the findings of a study to investigate changes in scholarly communication practices among a group of scholars in the UK and build upon the results that were published in a previous paper. Design/methodology/approach—The study deployed a naturalistic inquiry approach using semi-structured interviews as a qualitative research tool. A sample of 40 participants from four UK universities were interviewed to explore the changes in informal scholarly communication behaviour. Findings—The analysis of the interviews revealed that there are three ideal types of behaviour: the 'Orthodox' uses formal and traditional scholarly communication approaches; the 'Moderate' prioritises formal communication approaches, but at the same time is trying to get benefits from informal channels; and, the 'Heterodox' uses all channels available in scholarly communication.
