I wanted to read some older articles in the ‘xkcd What-if’ feed, as only “Drain the Oceans” was showing. I assumed the 14-day mark-as-read had kicked in.
However, when I switch to “All” (rather than “unread only”) I still only see one article in the list. Where are all the historical articles? I’ve been subscribed to that feed since I first signed up to NewsBlur many months ago.
