ACCOUNTING FOR USER INTERACTION WITH A SOCIAL NETWORKING SYSTEM WHEN NOTIFYING THE USER OF CONTENT PROVIDED TO A GROUP MAINTAINED BY THE SOCIAL NETWORKING SYSTEM INCLUDING THAT USER

A social networking system maintains various groups that each include one or more users and maintains information describing interactions by users with the social networking system. Based on interactions with the social networking system by the user, the social networking system determines a time interval when the user most frequently interacts with the social networking system. Additionally, the social networking system selects various content items provided to groups including the user based on amounts of interaction with content items provided to groups including the user by other social networking system users. During the time interval when the user most frequently interacts with the social networking system, information identifying a set of the selected content items is presented to the user via the social networking system.
