18. A method of displaying items related to a user selected tag, comprising: inferring, at a computing device, relationships between tags associated with tagged items, wherein the tagged items are one or more of posts of a question or answers to a question; receiving a selection of a tag on which to focus from a user; and, displaying a post area and an inferred-relationship display area, wherein the post area displays representations of a subset of the tagged items that are related to the tag, and wherein the inferred-relationship display area displays a representation of a group of tags related to the tag, wherein the group of tags only includes tags with above a threshold of relational closeness, wherein a closeness of an inferred relationship between the tag and an individual tag within the a group of tags is illustrated by a distance between where the tag is displayed and where the individual tag is displayed, wherein a shorter distance indicates a closer relationship, wherein tags within the group of tags displayed in the inferred-relationship display area are selectable by a user, and wherein a related tag becomes a new user selected tag upon a user selecting the related tag.

The method of claim 18 , further comprising: displaying a control for the user to change the threshold of relational closeness; receiving an input from the user through the control that increases the threshold of relational closeness; and updating the group of tags to include only those tags that satisfy the increased threshold of relational closeness.
