Here’s my list, included snippets of their own youtube descriptions.

Angela Collier theoretical physicist.

Andrew Millison is a permaculture teacher and practitioner.

Climate Town Rollie Williams and a ragtag team of climate communicators, creatives and comedians are here to examine climate change in a way that doesn’t make you want to eat a cyanide pill. Get informed about the climate crisis before the weather does it for you.

Crime Pays But Botany Doesn’t A Low-Brow, Crass Approach to Plant Ecology & Evolution as muttered by a Misanthropic Chicago Italian. We study plants through the lens of ecology and evolution, rather than what supposed anthropocentric uses they can provide (as if holding up the biosphere wasn’t enough).

Dr Fatima i went to grad school and all i got was this lousy understanding of systemic problems in science.

Meditations for the anxious mind

Noah Daniel interior & spatial design

Stewart Hicks Takes on Buildings and Cities.

Lost in the Movies - fewer than 10k subscribers, but he deserves so many more.

His work is generally on movies and TV, usually with a more art house feel.

His major piece of work though is his 30-40 part video series (and also podcast/blog) on Twin Peaks.

None of your, “Here’s the explanation of EVERYTHING,” nonsense here though.

Instead he looks at the show, its characters and its arcs with a contemplative eye, picking out interesting visual and narrative parallels, examining the show and film as a piece of art rather than as a puzzle to be ‘solved’.

It’s exceptional and it mystifies me that it’s not more well known. He’s been doing it for about ten years now I think. If you’re a Peaks fan, it’s an absolute must IMO.

Engels Coach Shop. Dude rebuilds wagons and other horse pulled things from piles of rubble. Really nice calm guy out in Wyoming.

Pat Finnerty breaks down bad songs in hilarious fashion.

Alpha Phoenix is a good science channel

Kari, she’s a retro gaming nerd, really young but absolutely knows her shit

Look Mum No Computer. An extremely talented musician who does videos around analog electronic music gear.

Mbmmllc. They do mining videos. The Kenya video is unbelievable and I learned so so much about the world from it.

Periscope Films. Stock footage that varies wildly

V. Birchwood, Historical fashion

Andy Ward’s Ancient Pottery, dude digs up clay and teaches you how to make pots in a campfire.

These are my picks.

LaurieWired - Cyber Security

Veronica Explains - Mostly Linux.

James Lee - animated videos

This is a fairly niche answer, but Noah Caldwell-Gervais.

He does very smart critical analysis of video games as a medium, often in multi-hour long retrospectives of entire franchises. They are all split into chapters, so it’s easy to watch in parts. The visuals and editing are not very flashy, pretty much just footage of the game he’s talking about, but they are so well written and thoughtful I find them extremely compelling. There’s also road trip travelogues, but I’m not as into those.

GothicLordUK a gaming YouTuber who plays a variety of rouge like and puzzle games.

Terrasteel a YouTuber who explains quirks and fun facts about Terraria.

Lance Hedrick makes really cool data driven videos about coffee.
