## Abstract

The disclosed embodiments relate to systems and methods for efficiently distributing content among a plurality of users which may be used to implement a social networking service. Content items, which may include “posts” submitted by one user, e.g. responsive to a “post” submitted by another user, are stored in association with data indicative of a specified subset of an interest category classifications defined by the system. Users of the system further specify a subset of the interest category classifications to define their interests. The system then provides content items of interest to the user by mapping, as will be described, the defined interests of the user against the interests associated with the stored content items. The disclosed embodiments enable users to discover and expand their interconnections with other users which may have similar interests.
