Maybe it's just me, but about 30% of YouTube just feels like this. It's kind of amazing to see different points of view, different experiences, and watch someone who mastered their hobbies.
I've been getting back into music after decades, learning how to write music instead of just playing it. I've probably watched a thousand hours of video over the last year, just watching whatever comes up. Hearing a wide variety of perspectives is insanely helpful, I really wish they were so easily accessible when I was younger.
