About Winnow

Winnow scores every post in your X timeline as you scroll and highlights the few worth replying to. Local, deterministic, read-only. Why this exists I was replying to the wrong posts. I used to reply to whatever showed up on the timeline, usually posts that were already ten replies deep, or three hours cold by the time I got to them. Same replies, just aimed at posts that were actually still open. The same reply is worth a great deal in the first fifteen minutes of a post with room left in it, and almost nothing on a post that already has forty replies and has finished being read.
