US Patent 8996625 Aggregate display of messages

In general, the subject matter described in this specification can be embodied in methods, systems, and program products for aggregating posts submitted to a messaging system. A server system identifies a plurality of posts that were submitted to a messaging system from a plurality of users with which a first user has an acquaintanceship relationship. The server system analyzes content from a body of each post to determine a group of the posts that each reference a common topic. The server system provides information so as to cause the computing device to display to the first user, in place of an individual display for each post in the group, an aggregate post that presents, as a primary entity, a second user of the messaging system that is affiliated with the common topic and that did not submit to the messaging system a post that referenced the common topic.
