1. A location-based search system that facilitates operation and performance of an online classifieds service comprising: a computer memory having stored thereon the following components executable by a processor: a receiving component that receives a query related to a search for one or more items listed through the classifieds service; a query component that processes the query across a set of geo-tagged items and outputs search results to a display device, wherein the search results include a subset of the items as a function of item location, wherein a geo-tag corresponding to the location of the item includes a latitude and longitude coordinate, Cartesian X,Y,Z coordinates, projections into two dimensional (2D) or three dimensional (3D) space, or other reference point information; a mapping engine that dynamically generates a virtual map of the subset of items outputted in response to the query, wherein the mapping engine reveals a portion of each item's location information to a user viewing the item based at least in part on the type of item being viewed; a discard monitor that collects information regarding a first item deleted from the search results by the user, informs an owner of the first item that the first item was deleted from the search results, and allows the owner of the first item to send a message to the user while hiding an email address associated with the user from the owner of the first item, wherein the message includes a request for direct feedback from the user as to why the user deleted the first item from the search results; an unopened-item monitor that collects information regarding which items were not opened by the user; and an artificial intelligence (AI) component that suggests one or more items from the subset of items for the user to view, select, or discard based in part on the user's historical data, activity, and preferences.
