ABSTRACT:
Techniques are described herein for notifying a member of a social network system of those changes, within the social network system, that are of most interest to the member. In one embodiment, change records are generated for changes in the social network system. The change records are stored in an activities log. To notify a particular user of changes that would be of interest to the user, a subset of the change records contained in the activities log is selected based on user-specific selection criteria. Once the subset of change records has been selected, a set of notification records is generated based on the subset of change records. To reduce the possibility of information overload, the subset of change records is consolidated by removing duplicates and merging related notifications. The consolidated list of user-specific notifications may then be sent to the user. A variety of mechanisms may be used to send the notifications to the user, including streaming the notifications to a user (e.g. via an RSS feed), placing the notifications in a web page that is sent to the user, and sending the user an email that lists the notifications.
