1. A system for generating a graph segment providing a gist or summary of an online social network conversation, the system comprising: a processor; a memory; a module stored in the memory and operable on the processor for generating a graph segment providing a gist or summary of an online social network conversation, the module being configured to cause the processor to perform a set of functions comprising: generating a graph of the online social network conversation, wherein the graph of the online social network conversation comprises a plurality of nodes and each node connecting at least one other node by an edge, each node representing a message of the online social network conversation and each edge corresponding to an action by a participant in the online social network conversation; determining an edge weight for each edge; analyzing the graph of the online social network conversation using at least the edge weight of at least some of the edges to generate a graph segment; and generating the graph segment, the graph segment comprising a reduced number of nodes of the graph of the online social network conversation based on analyzing the graph of the online social network conversation and the graph segment providing a gist or summary comprising an abbreviated view of the online social network conversation based on the analysis, each node of the reduced number of nodes corresponding to its own respective node of the graph of the online social network conversation.
