1. A method performed by data processing apparatus, the method comprising: identifying, by a data processing apparatus, a plurality of documents that have each been classified as documents that reference a particular member of a social network, the identification being independent of a request by the member of the social network; determining, for each of at least some of the plurality of documents and by the data processing apparatus, an entity score specifying a measure of importance of the particular member to the document, the entity score being determined, based at least in part, on a number of references in the document to the particular member, the references including instances of a name of the particular member; selecting, as a set of suggested documents for the particular member, a proper subset of the documents from the plurality of documents that have at least a threshold entity score; identifying an additional document that was not eligible for inclusion in the set of suggested documents based on the entity score for the additional document being less than the threshold entity score, wherein the additional document references the particular member; determining, by the data processing apparatus, that the additional document has a traffic spike score that meets a threshold traffic spike score, the traffic spike score for the additional document being a value determined based on a variance of user requests for the additional document over one or more specified time periods; including the additional document in the set of suggested documents based on the determination that the traffic spike score meets the threshold traffic spike score; providing, by the data processing apparatus, data that identify, in a social network page of the particular member, one or more documents from the set of suggested documents for dissemination, by the particular member, to other members of the social network; and providing, in the social network page of the particular member, a dissemination element that, upon interaction with the dissemination element, causes at least one of the suggested documents to be disseminated to one or more other members of the social network.
