Monthly ritual. November cohort: post your product (two lines: what + who-for), review the product above yours (use it for 20 minutes, real notes, kindness + honesty), receive a review from below. Chain unbroken since spring.
Rules: 20 real minutes (timers on, honor system, Hana's phone-answering energy applied), notes cover three things (first impression, one confusion, one delight), no drive-bys (review-givers who vanish get gentle notes, then firm notes, then Pieter's spreadsheet).
Sign up below with two lines. Reviews start Monday. The chain holds.
