43. A computing device configured to facilitate performance by task performers of tasks from task requesters, comprising: one or more processors; and one or more modules that are configured to, when executed by at least one of the one or more processors, for each of one or more task performers: obtain information about the task performer, the obtained information reflecting at least some prior activities of the task performer; receive indications of one or more available tasks supplied by one or more task requesters; automatically identify at least one of the available tasks as being preferred for the task performer based at least in part on an analysis of the obtained information about the task performer and on information about the identified tasks, wherein the analysis of the obtained information about the task performer includes weighting at least some of the obtained information about the prior activities of the task performer based on recency of the prior activities, such that a first prior activity of the task performer has a greater impact on the identifying than does a second prior activity of the task performer if the first prior activity occurred more recently than the second prior activity; and provide one or more indications to the task performer of at least one of the identified tasks.
