Interested, but won't subscribe without listening to at least one episode to get an idea of the content, quality etc. Is there a way to listen to the first (few) episodes as a trial?
I read the article. I’m still not sure what the podcast is about. What is it about?
Gruber hasn't said what it'll be about, but judging from the episodes list he links to, it seems to be roughly the same sort of content as on the Daring Fireball blog.
They appear to have started on this in mid-March, according to https://dithering.fm/, and the titles look to give a good sense of the subject matter.
Other than that, it looks like it's about 15 minutes.
