Swapping supplies.

Paul Levy with a simple (read: great!) idea:

We plan to have a general office supply swap for the hospital soon, but I thought I’d run an experiment in the meantime. It is based on my community experience running a soccer cleat exchange. I created the “Presidential swap shop” in the corridor near my office, which is within eyesight of a highly trafficked thoroughfare. The sign says, “Take what you need, leave what you don’t.” Already, within a couple of days, there has been a dramatic amount of trading activity.
