The more people involved in flying the airplane, or moving the surgeon's scalpel during a brain operation, the worse off we are. But this is not true in journalism. It benefits from participation, as with Investigate your MP's expenses, also called crowd sourcing, or this invitation from the Los Angeles Times: share public documents.
