In defense of Reddit (with regard to the Boston bombing, and crowdsourced sleuthing)

"Law enforcement agencies regularly turn to sites like to help crack cold cases. Maybe there’s hope for Reddit," writes Tim Murphy in a piece at Mother Jones.
Redditors have, for years, worked to use the resources of crowds as a force for good. There's an entire subreddit dedicated to Redditors ordering pizzas for families and raising money for surgeries. But Boston represents a reality check. Can Reddit harness its greatest asset—the tireless brainstorming of millions—while reining in the speculative impulse that makes the site tick? And even if Reddit could solve crimes, would it be worth it?
