The feed personalization module then provides a personalized feed including these content pieces to the user. The personalized feed is provided to the user via a unique identifier assigned to the user. Using the unique identifier, the user's actions with respect to the provided feed is tracked. The feed is further re-personalized according to the user's actions. The feed is also re-personalized based on an input from the user indicating the relevance of the feed to the user's interests.
