Abstract: A question is received on a first social network site from a first user. The question is sent to a second user of a second social network site who receives the question from the second social network site.

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.

Abstract: Systems and methods are provided to authorize users to anonymously access resources of different web sites. For example, a business listing service may authenticate users and allow the authenticated users to access the resources of the businesses listed via the business listing service, without the users having to create separate accounts with the businesses and without having to reveal the identities of the users to the businesses.

Abstract: Systems and methods sort location dependent information based on selecting multiple groups of information according to location, ordering the groups based on location, and ordering the information within the groups based on at least one or more other criteria. The size(s) of the areas used to select the groups may be predetermined, or dynamically determined (e.g., based on clustering of information along distance to a location of interest).

Abstract: Systems and methods are provided to facilitate search of listings of businesses according to opening date or age of the businesses at their current business locations. For example, a user may submit a search request for listings of new businesses (e.g., the businesses having the “Grand Opening” status) at a location specified by the user.

Abstract: Systems and methods are provided to specify a location of a planned event via a selection of a listing that has location information. For example, in response to a search request a listing may show a business entity at a geographic location; and the user may select the listing as a way to specify the location of a new event or an existing event. In some embodiments, one event can have multiple listings specifying multiple locations.
