On April 26, EchoEcho ran a small experiment at the Valley Eco Fair, hosted by Sustainable Stillwater MN.
The setup was deliberately simple: two boards - "Pass it on." and "Already reused." Visitors wrote a real item from home they'd let go on a sticky note with the price they wanted, and posted it on the first board. If someone else genuinely wanted it, they took the note and moved it to the second board.(No physical items changed hands - it was a simulation, designed to capture intent.)
Over 3 hours, ~50 people stopped by. They posted 41 notes, and 19 found a match in real time. Many came back later to check whether their items had been taken.
The hypothesis we wanted to test: if reuse is made this easy, will more of it actually happen?
The numbers suggest yes. The demand and supply for second-hand goods already exist within the same community - the friction of trading, and the lack of a tool to help people find each other, is what gets in the way.
This is exactly the principle EchoEcho is built on. Just at a community scale, instead of a folding table.
