For me personally it's easier to watch a video than to read a blog post or whatever these days. That's mostly because I can listen/watch while doing chores. However, if I need to use it later there's just no way I can find it or find what was in it. I like the format of Theprimeagen in particular when he goes over blog posts, I can always refer to that when I want to. So I'd say:
- videos as a replacement for written media: no
- videos as an addition to written media: yes
I think Supabase does this well. The documentation is there, videos are more specific and lengthy
If you're downloading manually there aren't really a lot of advantages to this I think, unless you search through 10 or more sites every time. For automated downloads using sonarr/radarr/lidarr/.. it's pretty mandatory.
