Abstract: A network computer system that determines metrics related to effort and cost on the part of deliverers who deliverer items for delivery orders. The network computer system can implement operations to facilitate or mitigate features that cause deliverers to expend effort or cost when completing delivery tasks.

Abstract: A network computing system can publish a collection of interactive items for a given geographical region. The network computing system can detect interactions with the interactive items by a population of users, where each interaction is associated with a location of the user, one or more food items identified for selection by the interaction, and one or more food preparation sources selected by the interaction. Additionally, the network computing system can determine an interest level for a food item or type at one or more sub-regions of the geographic region, based on at least a portion of the detected interactions.
