Methods and Systems for Accessing Relevant Content

A server system sends links to content categories for display on a user device associated with a user. Each content category corresponds to a subset of content items. When a link to one of the content categories is selected, the corresponding subset of the content items is sent for display on the user device. The system selects a group of content items according to determined relevance scores for the user based on one or more relevance criteria and sends links to the content items in the group for display on the user device in a first order according to the relevance scores. The system adjusts the relevance scores of some content items in the group according to user feedback and resends links to the content items in the group for display on the user device in a second order according to the adjusted relevance scores.
