That worked for you? I was having a devil of a time getting Feedreader to bring in that feed. I also had never touched Feedreader until last night and might have done something dumb. Inoreader did bring in the feed, but only after I "tricked it" (?) by doing a search for the feed; it wouldn't accept the rss URL. It all felt very mysterious and opaque.

I got word in the Ghost forums that there may also be an RSS feed bug, which I'll look into and see if that applies to this case.
