Is a video podcast a podcast? IMHO, yes. BUT… the show needs to be on RSS and be available for download on more platforms/apps than just YouTube.
If it’s just a YouTube video then let’s call it what it is… all together now… a YouTube video.
Nothing wrong with that, but it’s not a Podcast without an RSS feed.
Right @james@bne.social and @samsethi@podcastindex.social?
