A computer-implemented service analyzes collected data reflective of actions of users of an interactive system to identify items that are significantly more popular in specific user communities than in a general user population. The communities may, for example, include email-based communities (e.g., all users with email addresses associated with a particular company or other organization), shipping address based communities (e.g., all users with shipping addresses in Seattle), and/or communities based on other types of user attributes. The results of the analysis may be exposed to users to assist users in making item selection decisions, and/or may be used to provide item recommendations to users.
