We do have "little libraries" where anyone can take or leave books in many people's yards. But I haven't seen the honor system produce stands in urban areas for the past 10+ years.
Not complaining. It’s a neat concept. And if you have a bunch of crap you want to get rid, it’s a lot of fun to build a big birdhouse looking thing, prop it up on the side walk, and keep it stocked with all the crap you don’t want anymore. This is why I created the Little Free Lumberyard to discard my woodworking offcuts. Seriously considering expanding into e-waste because it works so damn well.
