Social networks have trained us to share all the superfluous details of ourselves, but a new app called Leftover Swap is trying to take things to the next level by allowing users to share leftover scraps of meals with one another.
Hungry, but too cheap to buy a $0.99 hot dog down the street? With LeftoverSwap you can just pull up a map of discarded meals in your area, make a selection, and then go pick it up from your neighbor.
