Abstract: A metadata item may be generated that includes metadata content corresponding to a selected portion of digital content stored on a first device, the metadata item may be associated with a first user profile, and the metadata item may be distributed to a second user device storing the digital content such that the metadata item can be accessed via a second user profile and rendered on the second user device in association with the digital content. In this manner, metadata content corresponding to digital content may be shared across user profiles that access the digital content. In addition, a collaborative content item may be generated that includes collaborative content associated with a word or phrase in digital content and that is editable by multiple user profiles.

Abstract: Electronic content such as an electronic book (e-book) that is referenced in or otherwise related to other content such as website content is identified, and a visual representation of the electronic content is generated. The visual representation is presented in conjunction with the website content, and a reader application for previewing the electronic content is launched via user interaction with the visual representation. Exiting the reader application causes a browser application that is rendering the website content to be automatically returned to a foreground state. A variety of actions are enabled via interaction with the reader application such as purchasing the electronic content, sharing the electronic content, or downloading a sample preview of the electronic content for later consumption.

Abstract: A system for updating a network accessible address book for a user is disclosed. The system includes a network address reference detection agent that detects a network address reference resulting from user interaction with a network addressable device. Network address references include e-mail addresses, SMS addresses, and telephone numbers. After the network address reference detection agent detects an event, a user identity data store is accessed. The user identity data store provides a reverse-lookup of one or more profile elements based upon the network address reference detected by the network address reference detection agent. The system also includes a capture agent for evaluating a business rule based at least on the network address reference. If the business rule is satisfied, the capture agent provides a prompt as to whether the one or more profile elements should be added at least in part to the network accessible address book for the user.

Abstract: Information aggregation techniques are described. In an implementation, a communication is received that includes an indication of a source of information associated with a non-member of the social network. Information associated with the non-member is aggregated from the source. The aggregation may be performed in response to receipt of a selection by a member of the social network service to interact with the information from the source. The aggregated information may then be presented to a member in conjunction with webpages output for interaction with the social network.

Abstract: A visitor to a profile page is invited to modify a user profile associated with the profile page. If the visitor elects to provide a suggested modification to the profile page, a message is transmitted to the user that owns the profile page requesting authorization to perform the suggested modification. In response to the message, the user can accept the suggested modification to the user profile, decline the suggested modification to the user profile, or edit the suggested modification to the user profile. If the user accepts or edits the suggested modification to the user profile, the user profile is modified accordingly. In this manner, a visitor to a profile page can assist in the creation of a user profile.
