Abstract: Systems and methods are provided to facilitate voice-based search of information. For example, a portable device may be in a first orientation to present a display of a graphical user interface, such as a search interface presented within a web browser of the portable device. When the portable device is in a second orientation different from the first orientation, the portable device records a voice input for the graphical user interface. When the portable device is back to the first orientation, the portable device applies the voice input to the graphical user interface. When the user shakes the portable device, the portable device re-initializes the graphical user interface for a subsequent input.

Abstract: Systems and methods are provided to advertise based on the postings of a user. For example, after receiving a posting from a first user, a web site may present the posting to a plurality of second users. A content analyzer identifies at least one topic based at least in part on the posting to select an advertisement. An electronic messaging system then delivers the advertisement to the first user and/or the second users.
