Bombing perspective

The power and limits of Twitter both become salient when there's a terrorist attack or other crisis. On one hand I found out about the bombings very quickly (actually from an office coworker who read it on Twitter, but I would've seen something there myself soon in any case); on the other, most of what then showed up in my Twitter feed in the subsequent hours was of little value. (I gather much traditional news coverage was not much better.) In any case, I recommend "The Boston Marathon Bombing: Keep Calm and Carry On" as a valuable perspective.
