I started to archive podcasts like Small Town Murder and Crime in Sports, but also downloading stuff from the BBC, I really like their audio dramas. I’ll probably expand to other podcasts once I find more good ones.
Also a bit off topic, but I also like to record/archive sports radio broadcasts.
It’s a great tool, but depends on what you expect from it and your use case. Personally I tried it but was always disappointed by it. I always just end up using SingleFile(Z) on my browser or in the cli along with the usual yt-dlp and the like and that’s all I need really. And if I need to save an entire site I just use wget or httrack. I don’t really have the need for a browsable archive of my saved pages, I usually order them by subject when saving.
