Other feedback:
For this HN Recap, 20 mins daily is a bit long, a 5-10 minute version would genuinely be part of my daily routine.
1 chapter/section per story would be cool, so that I can skip stories I'm not interested in. I listen to podcasts through PodcastAddict on my phone but tested this on Spotify web at my computer, maybe this is already in there & I just didn't see it.
Echoing what others said - I'd love for the general vibe of the comments to be included in some way, I actually tend to spend more time in HN comments than reading the articles themselves.
Finally, I'm sure this is on your radar already, but IMO the big opportunity with AI-synthesized podcasts is personalized podcasts. For example, a personal Hacker News Recap RSS feed that knows the kind of stuff I upvote, or has me opt in to topics/tags when signing up.
Is that a podcast? I don't think so. Is it authentic? Probably not but its not claiming to be anything but an ai tool, at least, but the whole thing you're doing is that your voice sounds more human than other ai voices.
Whatever it is, its not a podcast. It's ai generated summaries being read by an ai voice.
This concept, of creating a podcast using AI is exactly the kind of inauthentic thing podcasts got popular because of and as an alternative to. Crowd sourcing HN material to put through an AI tool for marketing buzz is the opposite of the impetus for podcasts. It fails as a podcast from the get go. You can't connect with this host - they don't offer opinions, they don't offer insight into their history or personality. There's no human on the other end, just a narrator regurgitating stuff a computer scraped from a website.
That the host sounds better than siri or google assistant doesn't redeem the concept which is bankrupt as a podcast from the get go.
