Abstract: A method for a computer system includes receiving a first user communication, determining a first group of users, determining a target number of users, determining whether the first group of users includes the target number of users, and if not, providing the communication to the first group of users, determining a hierarchal mapping of groups of users in response to user memberships, determining a second group of users from the hierarchal mapping, determining a plurality of social network relationship factors for the second group of users with respect to the first user, and providing the communication to at least a subset of users in the second group of users in response to the first plurality of social network relationship factors.

Abstract: A method for a computer system includes determining a first social distance for a first user with respect to a second user, determining a second social distance for a third user with respect to the second user, determining a first qualitative rating associated with the first user, determining a second qualitative rating associated with the second user, determining a first trust-metric for the first user in response to the first social distance and the first qualitative rating, determining a second trust-metric for the third user in response to the second social distance and the second qualitative rating, and prioritizing a first listing from the first user over a second listing from the third user for the second user, in response to the first trust-metric and the second trust-metric.

Abstract: A method for a computer system includes receiving a search request from a first user, determining a user identifier associated with the first user, determining a plurality of user identifiers associated with the user identifier within a social network, determining a first plurality of search request results of a plurality of users associated with the plurality of user identifiers, determining a list of results to the search request in response to the search request and to the first plurality of search request results, and providing the list of results to the first user as a response to the search request.

Abstract: A method for a computer server includes receiving search criteria from a first user at a remote client, receiving a first identifier associated with the first user, performing a search to determine a plurality of search results including a first and a second search result, determining a first rating from a second user associated with the first search result, determining a first social network indicia from the second user to the first user within a social network, determining a second rating from a third user associated with the second search result, determining a second social network indicia from the third user to the first user within the social network, providing the first search result to the remote client including the first rating and the first social network indicia, and providing the second search result to the remote client including the second rating and the second social network indicia.
