The tone of Monica Hesse's Washington Post story is somewhat snide. Although I did enjoy some of her word-play: "celebrademic" danah "uncapping" herself (altho note that the Post copyeditor re-capped her at the start of a para.) Frankly, "danah" uncapped has made proofreading PITAs for me for years. What is ignorant is Ms Hesse being surprised that small circles cite each other. This is true in many fields. There is a whole area of bibliometrics devoted to this. Check out the work of Howard White or Loet Leyesdorff, for example. Or, as usual, I have co-authored a paper on the subject -- its on my website. "Does Citation Reflect Social Structure? Longitudinal Evidence from the 'Globenet' Interdisciplinary Reserach Group" JASIST, 1/04. What is surprising is that I was interviewed and quoted by Ms Hesse and it was a much straighter piece of reporting: "An Unmanageable Circle of Friends: Social-Network Sites Inundate Us with Connections, and that can be Alienating." Washington Post, August 26, 2007, p. M10. http://www.washingtonpost.com/wp-dyn/content/article/2007/08/24/AR2007082400...
