Leave one. Take one. No feed, no profile, no audience. You give one, you get one — that constraint is the product. Pick a category, write something worth saying, and receive a stranger's contribution in return. Most apps let you consume endlessly; LOTO makes you contribute first. Messages people react to get surfaced more — quality rises naturally without moderators. Time-locked messages let you send words into the future. No accounts, no algorithms. Just one in, one out.
