1. A machine-implemented method, comprising: providing, by one or more processors over a network, a post generated by a first user of a user generated content service for display via a graphical user interface to one or more other users of the content service, the post comprising a representation of one or more items and the post being a single content item; receiving, by the one or more processors over the network, an indication of a request from a second user of one or more other users to suggest auxiliary content relating to at least one of the one or more items of the post; providing, by the one or more processors over the network, a search field and a search results area of a suggestion mechanism to the second user contemporaneously with displaying the post via the graphical user interface, the suggestion mechanism being added to the graphical user interface and allowing the second user to provide auxiliary content relating to the at least one of the one or more items, the search field to search for content separate from the post and the search results area to provide one or more results of the search; receiving, by the one or more processors over the network, via the suggestion mechanism displayed contemporaneously with the post, and responsive to the post generated by the first user, a suggestion provided via the search results area of the suggestion mechanism by the second user, the suggestion comprising auxiliary content relating to the at least one of the one or more items; providing, by the one or more processors over the network, the auxiliary content for display to the first and second users of the content service but not the one or more other users of the content service subsequent to the second user submitting the suggestion and prior to the first user accepting the auxiliary content; and providing, by the one or more processors over the network and for display to the first user, a mechanism comprising a first selectable graphical element to accept the auxiliary content and a second selectable graphical element to postpone viewing or accepting the auxiliary content to a later time; and providing, by the one or more processors, the post including the auxiliary content for display to the one or more other users of the content service in response to determining that the first user who generated the post has interacted with the mechanism to accept the suggestion.
