Jeremy Hunsinger writes a fictitious abstract regarding a paper that needs to be written by someone. The investigation would involve the validation/debunking of the Weblog power law meme and its implications. Alex Halavais provided the connection to Hunsinger's idea and amplified on the theme.
I completely agree with both gentlemen and would hasten to add that whatever one's stance in this debate, the foundations are still shaky. The methodology and data both strike me as bit suspect. There hasn't really been any independent validation. Also, the time varying aspects of these networks should prove interesting under scrutiny. Other than Andy Tomkins and crew, there doesn't seem to be a whole lot of action in this space.
