When I read my NewsBlur account via Unread.app on iOS I see posts from kottke.org, but I never added a subscription to that feed to my account. I originally thought this might be an Unread.app bug, but I did some more digging and I think it’s an issue with NewsBlur.
I do see it when I go to organize and select the flat view, but when I switch to the nested view it doesn’t show up in any folder.
I downloaded an OPML backup of my sites and kottke.org wasn’t in that backup either.
It looks like kottke.org is in my list of feeds but doesn’t live in a folder or even in the top level folder. The NewsBlur web app doesn’t show items from that feed, but Unread.app sees the feed and shows its posts.
My account username is farktronix and my email is email@example.com if you want to poke around at my account’s data on the server to figure out what’s going on.
