New Mario-Batali-endorsed app Feedie turns those socially shared food photos into meals for needy when you "check in" at a participating restaurant.

"Feedie taps into the prevalent compulsion many would-be food photographers possess to snap and share photos of their meals out, and channels that urge into a constructive way a to give back. Often a photo of a meal can conjure the taste, the smell , and the ambience of the experience, but now it can also produce a meal for someone else who truly needs one." -- Mary Godfrey, ABC News.com
