摘要

A user may subscribe to a content feed group that includes a set of content feeds. The content feed group includes a first set of content items from the set of included content feeds. The content items are presented in response to a subscription to the content feed group. After a change to a content feed group, such as an addition or a removal of a content feed from the set, a second set of content items, reflecting the changed set of content feeds, are presented.
