A user-interface method of selecting and presenting a collection of content items in which the presentation is ordered at least in part based on navigation and selection behavior of the user learned over time is presented. The method includes providing a set of content items each with an associated relevance weight and an associated actual person. The method further includes organizing the set of content items into groups of content based in part on actual groups of which the associated actual person is a member. The method further includes receiving the users navigation and selection actions and adjusting the relevance weights of selected content items. In response to subsequent user input, the method calls for selecting and presenting a subset of content items and content groups to the user ordered by the adjusted associated relevance weights assigned to the content items and content groups.
