Posts from the watchlist that no topic above claims.
Grouping by subject is the point. A reader gives you 45 separate streams and leaves you to notice that four companies wrote about the same scheduling problem this week; this page puts those four posts under one heading. Topics come from the filter terms already listed on the blogs-to-watch page, so the vocabulary is the course's.
Each post is scored by keyword against every topic, using its title and its summary, and it is filed under the topic it scores highest against. A term that names a subject on its own counts for more than one that merely co-occurs with it, and a match in the title counts for three times a match in the summary. Any second topic a post also matches is shown as a label beside it. The method is keyword matching rather than a model, which makes it predictable, cheap, and occasionally wrong.
Nothing on this page is required reading.
The index covers 45 sources from the watchlist. 37 publish a feed and are read from it; the other 8 publish none, so their index pages are scraped and each new post's own page supplies the title and date its card omits.

A date shown as "first seen" is not a publication date. Some sources publish no date at all, so the page records when the post entered the index instead of guessing.
