16. A method, comprising: establishing, with one or more computing devices, an adaptive topic marker with reference to a history of activity of a user, the adaptive topic marker comprising a hierarchical structure of a plurality of network locations for the adaptive topic; monitoring, with at least one of the one or more computing devices, for a change in status associated with the adaptive topic; updating, with at least one of the one or more computing devices, a query associated with the adaptive topic in response to the change in status of the adaptive topic to provide at least one updated network location associated with the adaptive topic; refreshing, with at least one of the one or more computing devices, the adaptive topic marker based at least in part on a relevancy of the at least one updated network location to the adaptive topic; comparing, with at least one of the one or more computing devices, a relevancy of the adaptive topic with a reorganization threshold; and reorganizing, with at least one of the one or more computing devices, a location of the adaptive topic marker with respect to a location of a static marker in a navigation page for display on a client device based at least in part on whether the relevancy of the adaptive topic exceeds the reorganization threshold.
