The system includes nodes interconnected by at least one data network. The nodes are organized hierarchically to comprise a root node and at least two child nodes. The root node stores a list of content items expected to be of interest to a particular user; transmits data reflective of an update for a subset of the list to at least one of the child nodes, the subset selected based on at least a predicted future location of the particular user and a geographic location of that child node; and receives data reflective of an update for the subset of the list from at least one of the child nodes. The at least one of the child nodes stores the subset of the list; determines an update for the subset of the list; and transmits data reflective of the update to the root node. ## Claims ### Claim 1 A system for maintaining content lists, the system comprising: a plurality of nodes interconnected by at least one data network;
