1. A computer-implemented method comprising:
identifying, by a computer system, a first content item to be provided to a client device of a first user; determining, by the computer system, that the first content item is capable of including a second content item that is contextually-related to the first content item; sending, by the computer system, a request to a social data system, the request comprising one or more criteria, and the social data system storing content items associated with members of a social network, and social affinity data representing connections among the members of the social network, the members of the social network including the first user and a second user; receiving, by the computer system, a social affinity graph of the first user, the social affinity graph defining a social connection between the first user and the second user, and the social affinity graph being based on input, from each of the first user and the second user, that identifies information represented by social affinity data to use in creating the social affinity graph; receiving, by the computer system and in response to the request, one or more candidate content items having criteria that match the one or more criteria, the one or more candidate content items having been created by one or more members of the social network who are in the social affinity graph of the first user; selecting, by the computer system, the second content item, from among the one or more candidate content items, the second content item having been created by the second user; altering, by the computer system, the first content item to include the second content item; and providing, by the computer system, the first content item, which has been altered to include the second content item, to the client device. |
