Abstract: A score is generated for each of a plurality of potential user groups in which to add the first user, each potential user group containing a plurality of users, the score based on a location of the first user. The first user is added to a first user group based on the score generated for the first user group. A pinning action by the first user pinning the first user to the first user group is then received. A change in location of the first mobile device is detected, and the score of each of the potential user groups is regenerated based on the changed location, causing a determination that the first user should be removed from the first user group. The first user is maintained as a member of the first user group despite the determination that the first user should be removed based on the pinning.

Abstract: Systems and methods for the forming of user device groups are presented. In one example, logical relationship information describing logical relationships among a plurality of users is accessed. Potential membership of a first user in a first group of users is determined based on scores generated for each of a plurality of possible groups of users, the scores based on the logical relationship information. Then the first user is added to the first group of users. Content from an electronic device of the first user is received for broadcast to the first group of users. In response to the receiving of content, the scores for each of the plurality of possible groups of users are regenerated based on the content. Then the first user is added to or removed from a second group of users selected from the plurality of possible groups of users based on the regenerated scores.

Abstract: Systems and methods for the measuring of affinity levels via passive and active interactions are provided. A first group of users are selected from a plurality of possible groups of users. Affinity levels are measured among the users of the first group, the affinity levels based at least partially on both passive and active interactions between an electronic device of a first user and electronic devices of users in the first group. The first user is added to the first group based on the affinity levels.

Abstract: Systems and methods for the forming of user device groups are presented. In one example, potential membership of a first user in a first group of users is determined, the first group of users containing a plurality of users, by selecting the first group from a plurality of possible groups, the selecting being based on scores generated, for each of the plurality of possible groups, the scores based at least partially on the a loneliness score for the first user, the loneliness score being an estimate of how lonely the first user is and being calculated by examining past communications between an electronic device of the first user and other electronic devices via a social network service. The first user is then added to the first group of users based on the loneliness score. Content from a second user in the first group of users is received, and then the content is distributed to users in the first group of users.

Abstract: Example systems and methods of content sharing via social networking are presented. In one example, availability of a first user device to provide media content over a communication network is detected. A second user device is identified via an association of the first user device with the second user device that is specified in a social network. An acceptance by the second user device to receive the media content from the first user device is determined. In response to the acceptance, transmission of the media content provided by the first user device over the communication network to the second user device is initiated.

Abstract: In an example embodiment, a message comprising location information indicating a geographic location of a first user device is received. Then environmental information indicating at least one physical environmental condition in the vicinity of the first user device, as detected by an environmental sensor is received. Values representing logical connection strengths between a first user of the first user device and other users, the logical connection strengths based, at least partially, on the location information and at least partially on the environmental information, are calculated. Then a second user and a third user to form a group with the first user are determined, based on the values representing the logical connection strengths. A user group is formed containing the first user, the second user, and the third user. Content is received from the first user device and transmitted to users of the user group.

Abstract: In an example embodiment, logical relationship information describing logical relationships between a first user and other users is recorded, the logical relationship information associated with a social networking service. Then affinity levels for each of the logical relationships between the first user and the other users are calculated. One or more of the logical relationships between the first user and one or more of the other users are displayed in a user interface, wherein the affinity level for each of the one or more logical relationships is represented graphically in the user interface.

Abstract: Systems and methods for the transmission of content are provided. A user group is defined and a group data structure corresponding to the user group is stored. An item of content is received and stored as a child data structure of a parent data structure of the group data structure. In response to this storage, the item of content is automatically transmitted to all other users of the user group.

Abstract: Systems and methods for the forming of user device groups are presented. In one example, a message received at a user device from a server system, the message indicating that a user of the user device has been added to a logical group of users. Then content may be transmitted from the user device to the server system for distribution to the logical group of users. Then, in response to a determination that the user device has been out of communication with the server system for a predetermined period of time, a determination is made, utilizing a coasting module on the user device, that the user should be removed from the logical group of users based on a factor other than a length of time the user device has been out of communication with the server system.

Abstract: Systems and methods for the forming of user device groups are presented. In one example, a message including location information indicating a geographic location of a first user device is received from the first user device. Values representing logical connection strengths between the first user device and other user devices are calculated using the location information. A first device group is determined for the first user device based on the calculating of the values representing the logical connection strengths, the first device group including a plurality of the other user devices.

Abstract: Content is received from a first user. Then, in response to the receiving, logical relationship information describing logical relationships among a plurality of users is accessed and potential membership of the first user in a first group of users is determined based on the logical relationship information, by selecting the first group from a plurality of possible groups, the selecting being based on scores generated, for each of the plurality of possible groups, by a candidate scorer module. Then, in response to a determination that the first group has a score from the candidate scorer module that does not meet a preset threshold, a new group is created comprising users that are located proximate to each other. The content received from the first user is forwarded to other users of either the first group or the new group, based on the threshold determination.

Abstract: In one example, a first group of users is selected among a plurality of possible groups based on a score generated for the first group, the score indicating appropriateness of the first group for the first user, the first group of users having a plurality of users. A first user is then added to the first group of users. Then, affinity levels between the first user and other users in the first group of users are measured, the affinity levels indicating how strong logical relationships are between the first user and the other users in the first group of users. The first user is then removed from the first group of users in response to a determination that the affinity level between the first user and the other users in the first group of users has dropped below a preset threshold over time.

Abstract: The invention provides a technique for assigning a server to manage resources. The server identifies a capacity value that represents a maximum number of resources that the server can simultaneously manage, and parses data included in a tracker directory to identify the resources that have the fewest number of servers assigned to manage them. Next, based on the capacity value, the server registers to manage the identified resources, where each registration to manage an identified resource results in the server actively managing the resource when no other server is registered to manage the resource, or acting as a backup manager to the resource when at least one other server is registered to manage the resource, and the tracker directory is updated accordingly. Finally, the server, for each registration that results in actively managing a resource, configures itself to process client device requests that are directed to utilizing the resource.
