Cluster-based friend suggestion aggregator

Techniques are described to generate a list of suggested friends for a client of a social networking service. In an implementation, a cluster of clients is identified from among the clients of the social networking service. The cluster of clients includes the client for which the list of suggested friends is to be generated. The list of suggested friends for the client may then be generated and may include one or more clients of the social networking service selected based on connections with the cluster of clients. The list indicates at least one other client of the social networking service that is suggested as a friend.
