A feed is a promise that there will always be more. It is also a promise that nothing will ever be finished. The form is designed to prevent the small satisfaction of an ending — the bottom of a page, the last track, the credits.

We talk about feeds as if they were pipes, neutral conduits for whatever we choose to put in them. But every pipe has a shape. The feed’s shape is infinite, and infinity changes what we expect from a day.

The end as a feature

Older media were bounded. A newspaper had a last page. A record had a final song. Those boundaries were not limitations; they were cues that told you when to stop, and stopping is how experience becomes memory.

A feed gives you everything except the feeling of having finished.

Some of the most interesting new products are deliberately finite: newsletters that end, apps that close at midnight, playlists with a fixed length. They are not anti-technology. They are pro-conclusion. In a culture of endlessness, an ending is a luxury good.
