Information aggregation techniques are described. In an implementation, a communication is received that includes an indication of a source of information associated with a non-member of the social network. Information associated with the non-member is aggregated from the source. The aggregation may be performed in response to receipt of a selection by a member of the social network service to interact with the information from the source. The aggregated information may then be presented to a member in conjunction with webpages output for interaction with the social network.
