Abstract
Retrieving content items based on a social distance between a user and content providers. The social distance is determined based on, for example, user interaction with the content providers. The content providers are ranked, for the user, based on the determined social distance. Prior to a request from the user, the content items are pre-fetched based on the ranked content providers and constraints such as storage space, bandwidth, and battery power level of a computing device of the user. In some embodiments, additional content items are retrieved, or retrieved content items are deleted, as a variable-size cache on the computing device fills or changes size.
