"[I]f Reddit is actually interested in using the power of its crowd to help the authorities, it needs to dramatically rethink its approach..."

"... because the process it used to try to find the bombers wasn’t actually tapping the wisdom of crowds at all—at least not as I would define that wisdom. For a crowd to be smart, the people in it need to be not only diverse in their perspectives but also, relatively speaking, independent of each other. In other words, you need people to be thinking for themselves, rather than following the lead of those around them.... The problem from Reddit’s perspective, of course, is that this method of sleuthing would be far less exciting for users, and would probably generate less traffic, than its current free-for-all approach."
