A crowdsourced hunt for the bombers was unambiguously counterproductive
...There’s an art to working out where to find fast and reliable information, and to judging new information in light of old information, and to judging old information in light of new information. And there’s an art to synthesizing everything you know, from hundreds of different sources, into a single coherent narrative. It’s not easy, it’s not a skill that most people have, and it’s precisely where news organizations add value.
But in this particular case, as Noah Brier points out in a post headlined “Being Part of the Story”, it’s something that millions of people ended up attempting to do, on the fly, anyway:
"Everyone wanted to be involved in “the hunt,” whether it was on Twitter and Google for information about the suspected bomber, on the TV where reporters were literally chasing these guys around, or the police who were battling these two young men on a suburban street. Watching the new tweets pop up I got a sense that the content didn’t matter as much as the feeling of being involved, the thrill of the hunt if you will. As Wasik notes, we’ve entered an age where how things spread through culture is more interesting than the content itself."
