Abstract: A system and method for the federation of content items of a social network based on personalized relevance includes obtaining content items from first and second content item sources. Profile data for a member of the social network is obtained from the electronic data storage. A relevance score of the content item to the profile data of the member is determined for each of the content items. A utility value is determined based on the selection value, the value metric for content items from the first content item source, and the relevance score. A user device associated with the member displays the content items based on their respective utility values.
