Quiet posts about what we're learning as we build fold in: design choices we second-guess out loud, findings from real Folds, and the occasional argument with the idea of a marketplace.
We almost shipped a two-tap handoff. Then we ran a tiny test: pairs of beta users trying to remember, a day later, whether the handoff had happened. The number of "I think so?" answers scared us into the code.
There's almost always one tiny gotcha that needs to be passed along with a lent thing. We built a 280-character field for it, and it became the most-used field in the app.
We banned every red badge from the incident flow. The numbers on what happens when you do are still surprising us.
If the model gets the title wrong, the experience falls apart. So we built a "Not quite" branch that's almost as fast as the right answer.

A meditation on Etsy, Craigslist, and why your great-aunt's bread machine doesn't belong on either of them.
