Abstract: Method and apparatus for controlling delivery of an item. An electronic order specifying the item is received. An item profile for the first item is retrieved. A first instance of positional data for the user and a pattern of delivery preferences of the user are determined. Embodiments determine a first location for delivering the package to the user, based on the item profile, the first instance of positional data for the user and the pattern of delivery preferences of the first user. Shipment of the first item towards the first location is initiated, and based on subsequent network communications with an electronic device associated with the user, a second instance of positional data is determined. Delivery of the first item is facilitated to one of the first location corresponding to the first instance of positional data and a second location corresponding to the instance of positional data.

Abstract: This application describes systems, methods, and techniques for presenting supplemental information. The systems, methods, and techniques described herein determine that a message includes a keyword and, based at least on the identified keyword, determine at least one item to recommend. The message can be annotated with an identifier of the recommended item, and responsive to activation of the identifier, the supplemental information regarding the item can be presented.

Abstract: Functionality is described herein for presenting supplemental information. The functionality determines that a message includes a keyword and, based at least on the identified keyword, determines at least one item to recommend. The functionality annotates the message with an identifier of the recommended item, and responsive to activation of the identifier, presents the supplemental information regarding the item.

Abstract: Functionality is described herein for presenting a sequence of messages to the user arranged in chronological order. The functionality additionally annotates the messages with identifiers. Some of the identifiers convey the manner in which the identified messages relate to other messages in the sequence. The functionality therefore uniquely combines the merits of both a flat paradigm for organizing messages (by virtue of the arrangement of the messages in chronological order) and a nested paradigm for organizing messages (by virtue of the linking identifiers added to the messages).
