I'm the same. There's just one podcast I like (Loremen, with Alastair Beckett-King and James Shakeshaft) where I'll rarely (re)watch a video version. Normally it's a two-hander (or the hosts and a guest) and so purely audio, all good, but every now and then they do a live show and if they film it I'll watch that for the audience interaction, cos it feels like almost a different beast. But that's prob only one ep in 30.

Podcasts must be two things to me to classify as such:

1- They must be primarily audio. If they also happen to be available as a video, so be it, but if any of their production doesn't work because it relies on a visual element, then it's a video chat show / essay and if I'm interested I'll watch it via PeerTube/YouTube.

2- They must be available via RSS in a general purpose podcatcher app. If your podcast is only available on Spotify and has no RSS feed to which I can subscribe, then your show is paid-for content and not a podcast and I won't listen to it.

the two that in particular inspired the above grumble (60 Songs and One Song) used to be proper podcasts (60 Songs never had video until very recently; One Song I don’t know but never leaned into it) is there more ad money in video I wonder

I suspect the money aspect is a part of it, but also it's where the audiences are I guess.

One of the lads at work listens to my show - and is the sole reason I went to the trouble of setting it up on Spotify. But because they pull the show every week for copyright reasons, I ended up having to teach him how to subscribe via RSS in the iOS Podcasts app.

There's a part of me that wonders about uploading it to PeerTube as well - or instead of Mixcloud.

Then it's not a podcast. It's a video.
