1. A computer-implemented method of identifying information of interest within an organization, wherein the organization includes a structured body of users with associated roles within the organization and who have access to information items within the organization, the method comprising: determining use data that characterizes relationships among the information items and relationships between the information items and users within the organization, wherein each information item is a document, a presentation, a video, an image, or a webpage, wherein a relationship between a first user and a first information item corresponds to activities performed by the first user on the first information item; wherein the activities include at least five of: querying, browsing, opening, editing, bookmarking, collecting, or curating the first information item; and, wherein the use data is determined in part by tracking which information items or portions of information items users interact with; generating interest data indicating affinity among the information items based on the determined use data, wherein generating the interest data includes identifying at least one set of two or more information items that are frequently viewed together, where each set of information items includes a first information item from the set of information items and a second, different information item from the set of information items; using the interest data to create a feed of information items ordered by relevance to a particular user; and providing the feed of information items to the particular user.
