I've actually considered starting a YT channel myself at some point. Content would be whatever I'm feeling at that moment and not anything specific; one video could be Marxist theory, another could be the history of some ancient culture I happen to have an autistic fascination with, another could be a review of a video game - y'know, just whatever I'm feeling at the moment.
I won't be doing this anytime soon as I have to resolve some gender dysphoria stuff first before I'm willing to put my face on camera but it's on my to-do list. I feel like video essays are a better medium for talking about things than blogposts, at least for me with my ADHD and autism.
