Well, I guess just to list off who I watch frequently, kinda sorted into categories:

TTRPG:

• Critical Role - Really famous. Live-play of TTRPGs. It’s really a huge investment of time to keep up with it, though.

Just people I have parasocial relarionships with:

• Any Austin - Kinda “philosophy of gaming” is how I’d describe his latest content. I’ve been a huge fan of his for many many years and am way more invested in him than the content he currently makes. But he’s really fascinating. His alternate channel “The Excellent Man From Minneapolis” is music he writes/records. Good stuff as well IMO.
• Memoria - Gaming entertainment content. Found her when she was featured on Austin’s channel.
• gl;hf - A podcast that Austin and Memoria do together. It’s about everything and nothing.

Long form deep dive investigative and social commentary stuff:

• OKI’s Weird Stories - Cool expos on things like conspiracy theories and cults.
• Fredrik Knudson - Similar cool expos on things like gaming communities, fandoms, niche infamous figures, scientific experiments, etc.
• Folding Ideas - Somewhere between expos and social commentary. Does stuff about flat earthers, gold, cryptocurrency, etc.
• Contrapoints - Insightful and really well-edited/highly-prodiced left-wing social commentary stuff.
• Philosophy Tube - Quite similar to Contrapoints but different. I’d imagine if you like one, you’d like both.
• Munecat - Also similar to Contrapoints and Philosophy tube.
• Innuendo Studios - Maybe discontinued, but really really good source for info on how the alt-right “works” and how to fix (particularly American) fascism.

Tech/hacking:

• Ben Jordan - Stuff about privacy, police tech, fighting scraping for gen-ai training, etc. Informative.
• Marcin Plaza - Hobbyist mobile computing device prototyping. Quite entertaining as well.
• James Channel - Fucking hillarious. Mostly game system modding content, but way funnier than that makes him sound.

Satanism:

• The Satanic Grotto - A small satanist group based in Kansas that made the national news big time not too long ago holding a “black mass” at the state capitol. I’m just fascinated by all the legal fallout of the whole thing. And… I think the Satanic Grotto is the good guys. “Part of the solution” if you will.
• Behemoth X - Just really dark and atmospheric content about rituals to commune with demons. Dude 100% believes demons are real and powerful and he does blood sacrifices to them and talks about what wisdom he claims they’ve shared with him. Also life advice. Lol. Really interesting. Only major downside to the guy: he’s really leaned into using AI art in his videos lately. It’s pretty cringe.

Other creepy stuff:

• Tales From The Trip! - Substance use trip reports. Only bad trip reports.
• Night Mind - Essays on horror media. Mostly video games and ARGs.
• Nexpo - Similar to Night Mind, but occasionally does stories about grisly murders or creepy cults.
• blameitonjorge - Similar to the above, but with a lot of focus on lost media.
• Nick Crowley - Mostly creepy internet and TV history rabbit holes.

Vidja gaming content:

• Summoning Salt: History of speedrun world records. Way more interesting than it sounds.
• Pointcrow - Bit of a guilty pleasure. Popular Twitch streamer who does speedruns and challenge runs and stuff. Quite entertaining, but a bit sophmoric.

I’m sure I could think of more if I thought for a bit. I should mention that I don’t usually log in to YouTube. I keep my subscribed-to list in NewPipe on my phone. But I also do a fair amount of just searching by topic or happening across YouTube content on Lemmy or Hackaday.
