The Neighbor Experiment

What if the people living closest to you didn't have to be strangers?

I left a note on 40 doors in my building. 16 neighbors joined a group chat. Now I want to see if it works in other buildings, streets, and cities.

How it works
You leave a simple note for your neighbors (I'll send you the template). If you share your location, I'll group you with other participants nearby so you can compare what's working and what's awkward.
