The New York Times reports today that it tends to take 36 hours for half the total readership of an online article to read it–and, by the definition of the study in the journal of the American Physical Society, to become "old news." The research was based on readers at a Hungarian web site origo.hu, so perhaps Americans are different. The researcher does say he was surprised by his results, since "traditional ideas about the way people use the Internet would have led researchers to expect a much shorter half-life, more like two to four hours." Certainly, the comment pattern on Hit and Run seems to indicate a much shorter half-life for posts here, closer to that two to four hours than 36. Of course, we are such bloggin' machines ovah heah that our posts rarely stay on the front page that long anyway.
