You see an abandoned on the city street. You list it. Anyone can claim it. Basically we've developed an app that whenever you see something like a couch, TV, BBQ, etc. that's been dumped on a street corner, you whip out your iPhone and take a picture of it. The item goes onto a big map, so that anyone can browse and get it for free!
A map of all Chicago recycling drop off locations for residents who live outside of the city's blue cart service zone. The city's website only shows a list of addresses which I found pretty useless. I also set up a mobile version of the site so you can recycle on the go!
