On the subject of feeds, I have removed the Blubrry PowerPress plugin so the site will no longer advertise a feed for the old microcast.
I'm not ruling out using audio again in the future but I think it will be a lot more ad hoc and nothing episodic that requires a separate focus.
I went back and edited out all the PowerPress specific tags from the microcast posts so that they continue to display correctly but found that episode 22 appeared to be missing, at least the post for it. The audio file is in the media library yet the accompanying post that should have been on 27th May 2017 is not there.
Maybe I'll link to it in a future post.
