A swarm can develop around a piece of content. The swarm can include the original content, changes to the original content, the persons contributing the changes, and metadata, such as comments contributed by members of the swarm. A swarm can also include statistics generated about the content, such as the size of the swarm, the growth and/or death rates of the swarm, the longevity of the swarm, the intensity of the swarm, the persistence of the swarm, and the direction of the swarm. Swarms and their behaviors can be used to validate or invalidate content.
