Chris Csikszentmihályi in the Columbia Journalism Review on Looking for Haiti’s Lost, Online:
A blog or BBS (bulletin board system) is great for chronologically ordering stories or conversations, but the serial format leaves much to desire for exhaustive searches, and two blogs are more than twice as bad. If a cousin of “Jean Deaux” posts that she is looking for news of Jean on one site, and Jean’s friend posts that he is safe on a different site, the cousin might never see it. The greater the number of sites posting lost or found information, the less chance there is that the right people can connect. According to Reed’s Law, the value of a network grows exponentially with the number of its members. Silos, while great for grain, are terrible for information. What is called for is open, interchangeable data.
