@robb I'm not sure why subscribing to your own feed didn't work though, it should be exactly the same experience as subscribing directly on the page linked in the profile.
Fwiw, I subscribed to your feed fine using Inoreader. What reader are you using?
@paulcuth Apologies - you are doing exactly what I thought (in my tired state I must have looked at it wrong). I think what's happening is NetNewsWire isn't looking for a feed because the URL ends with .xml
And apologies for the title thing, again I think this might be a NNW issue not looking for the actual feed.
