I built a shared wall that can't be spammed, by removing the text box

Why the Positivity Wall has no text field, no accounts and no likes — and what subtraction has to do with building alongside AI.

I spent a day making a website easier for search engines to find, and finished it by
building a page that has nothing to do with search engines. Nine panels. You click one,
you leave a stamp, and the stamp is still yours the next time you come back.

The interesting part isn't the feature. It's the three things I took out.

The first version was worse

The original idea was a 3×3 grid of embedded videos from people who make cheerful
things — reposted on my site. I talked myself out of it in about ten minutes, for a
reason that turned out to matter: embedding someone else's video sends my visitor to
their platform. It borrows nothing and gives away the only thing I have.

So the content had to come from the visitor. And the moment content comes from
visitors, you're running a moderation problem whether you meant to or not.

Why there's no text box

The obvious design is a text field. Leave a nice message. I didn't build that.

Three characters is enough for a slur. Any free-text field on a public page is a
commitment to moderate it forever, and I'm one person who won't always be paying
attention. A field I can't supervise is a field I shouldn't ship.

What I built instead is a stamp generated from a random seed in your browser:

// seed -> shape, glyph, hue. no assets, no storage, no input.
function rnd(s) { s = (s * 9301 + 49297) % 233280; return { s, v: s / 233280 }; }

function stamp(seed) {
  const r = seq(seed, 4);
  return {
    hue:   Math.floor(r[0] * 360),
    sides: 3 + Math.floor(r[1] * 5),   // triangle .. heptagon
    rot:   Math.floor(r[2] * 360),
    glyph: Math.floor(r[3] * 4)
  };
}

You can't type anything. You can't be obscene with a hexagon. And the stamp is more
personal than initials would have been, because it's yours and you didn't choose it.

Identity without accounts

No sign-up. No name. The page doesn't know who you are and has no way to find out.

What it has is one integer in localStorage. That's enough to say this mark is yours
and welcome back, and nothing else. Clear your browser and you become a new person,
which feels correct.

Shared state runs on playhtml, which is CRDT-backed — two people
stamping at the same moment both land, with no server I run and no database I have to
secure. The less I store, the less there is to leak.

What this has to do with AI

I build alongside AI constantly. What I notice is that the tools are very good at
producing more — more pages, more features, more words — and the discipline I keep
having to apply is subtraction.

The wall could have had comments, likes, leaderboards, streaks, a login. Every one was
available and cheap. Every one would have made it worse: more surface to moderate, more
data to hold, more reasons to visit out of obligation instead of pleasure.

Joy in software isn't a feature you add. It's what's left when you stop adding things
that create obligation.

Credit

The premise isn't mine. It came from Amanda Gore and The Joy
Project, whose work is about
helping people reconnect with themselves and each other. Her version happens in rooms
full of people. Mine is nine rectangles and some SVG — but the mechanism is the same
one she's pointing at: a person feels better when they're briefly, specifically seen.
