1. A computer-implemented method comprising: obtaining, by one or more configured computing systems of a group discussion prediction service, information about a distributed group discussion involving a plurality of users, wherein the obtained information includes first information about a plurality of content items already submitted by the plurality of users during one or more time periods and includes second information about one or more predictions by the group discussion prediction service regarding future content items that will be submitted by users for the distributed group discussion during one or more future time periods; selecting, by the one or more configured computing systems, multiple factors to use in summarizing the obtained information for each of multiple time periods that include the one or more time periods and the one or more future time periods, wherein the multiple selected factors include a total quantity of content items supplied during each of the multiple time periods and include a rate of change in total quantity of content items supplied between two or more of the multiple time periods; determining, by the one or more configured computing systems, multiple visual aspects to use to display information about the multiple selected factors to one or more users, wherein each of the multiple selected factors is associated with one of the multiple visual aspects, and wherein the multiple visual aspects include sizes of displayed items, vertical locations or movements of displayed items, halos or shadows associated with displayed items, and colors of displayed item; generating, by the one or more configured computing systems, information for display that is based on at least some of the first information and on at least some of the second information, the generated information including, for each of the multiple selected factors, a summarization that is represented using the associated one visual aspect for the selected factor and that is based on a subset of the obtained information that corresponds to the selected factor; and initiating, by the one or more configured computing systems and before the one or more future time periods, display of the generated information to the one or more users.
