I like listening to Cose Molto Umane (it's also available on all podcast apps).
The host talks about fan facts and origij stories behind ordinary things.
Comes out every day and it's under 10 min am episode.
I agree and it would be much better if people would use Signal instead of WhatsApp, but I think there's still one problem.
Due to how messaging platforms work, every time you switch you lose pretty much everything (messages, media, etc)
This makes switching very hard even for a nerd like me, because if Signal is not "perfect" it means that I will have to switch again at some point and lose everything again.
I love this game so much.
