Write to a Stranger: Why Postcards Beats Another Chat App

Every language app eventually hands you the same thing: a list of strangers and a blank message box. And most people, faced with that, type "hi" to eleven people and hear back from none. The problem is not shyness. It is that "hi" carries no information, so there is nothing to answer.

Postcards is our answer to that, and it works by taking the choice away. You get a prompt — what can you see out of your window right now?, teach me a word your language has and English does not — you write a few lines, and you tie it to a balloon. You do not choose who reads it.

Why writing to nobody is easier than writing to somebody

A message addressed to a named person with a photograph is a performance. You reread it. You wonder if it is too long, too eager, too obviously a learner's sentence. A card going into the sky is none of those things, and people write far more honestly on one — which is exactly the state you want to be in when you are practising.

It is also the right length. A postcard is 420 characters. Long enough to make a real sentence and use a tense you are unsure about, short enough that you will actually finish it on a bus.

The part other apps throw away

When you send a message into a void, you learn nothing. Our cards keep their journey: everybody who opens yours stamps it with their country, and you watch the trail grow — three countries, eleven hours, two letters back. If somebody opens it and does not feel like writing, they let it fly on, and it carries their postmark to the next pair of hands. Nothing is a dead end.

That turns out to matter more than it sounds. A reply rate of one in five is demoralising when four messages vanish; it is fine when the four that did not answer still show up as stamps from Osaka, Bogotá, Lyon and Cork.

It drifts to people who can actually help

A card does not go to a random account. It drifts towards people who speak what you are learning, and whose own target language is one you already speak. So the person most likely to open your shaky Japanese is somebody who can answer it — and who wants your English in return. That is the whole idea behind a language exchange, applied to writing instead of to a contacts list.

How it works, in full

• Eight a day. You can open eight balloons in a day. The count comes back at midnight and the sky shows the countdown. Scarcity is the point: eight cards you read properly beat a feed you scroll.
• Three in the air. Three of your own cards can be flying at once, so you write when you have something to say rather than to fill a quota.
• Nearly anonymous. A card shows two letters of a first name and two rows of flags. No photograph, no profile, no age. You are answering what somebody wrote, not who they look like.
• Two letters make a chat. When you have both written to each other, the thread moves into your chats on its own and the anonymity lifts. That moment is the product.
• Written by people. Every card passes the same filter the rest of the site uses, the house rules apply, and a reported card comes out of the sky immediately.

What to write on your first one

Answer the prompt literally and concretely. "What can you see out of your window" should get a mango tree and a neighbour arguing with a cat, not "I see the city". Detail travels; opinions do not. A stranger in Poland has no way into "I like travelling" and every way into "the tram outside my window has squeaked at 6:40 every morning for a year".

Write it in the language you are learning if you can bear to, mistakes and all. The people it reaches are learners too — that is who the sky is full of — and a card with a wrong tense in it has never once stopped somebody replying.
