I only really subscribe to two channels that focus on 20-30 minute videos and post on a pretty regular basis:

Technology Connections

Internet Comment Etiquette with Erik

There are two YouTubers who make videos 4+ hours long that you have to watch every minute of:

Jenny Nicholson

HBomberGuy

Angela Collier for commentary on physics. She has a lot of good commentary on the field itself (see her recent Feynman video), but also good science videos... that I usually lose track of about 3/4 of the way through, but I enjoy nonetheless.

Along with Technology Connections, Philosophy Tube, and Primitive Technology, here are my "must watch" subs

Climate Town - Excellent videos about climate change and environmental impact that are insightful and funny

Contrapoints - Well written and meticulous deconstructions of philosophical concepts in media, pop culture and society with a dry wit

Every Frame a Painting - Amazing content on film-making. No longer active, but if you haven't seen it yet, lucky you, enjoy.

Pop Culture Detective - Interesting meta analyses of popular tropes in pop culture

Because I'm into historical clothing and fashion, Bernadette Banner and Abby Cox both do great videos on costuming, history and creating cool stuff

• hbomberguy
• Folding Ideas
• Harvard Math
• MIT OpenCourseWare

Technology Connections

I actively avoid shorts so most of what I watch is long form.

• Technology Connections - A guy needing out about household tech
• Unlearning Economics - a trained economist turned public edutainer who kept learning after Econ 101, unlike others who shall remain nameless
• Behind the Bastards - Chummy laughter about the worst people ever
• RPG with DBJ - RPG talk with a focus on creativity and exploring the opportunities afforded by the space of 'limited only by your imagination'
• We're in Hell - A guy looking at pieces of media and the ideology infused into them by culture
• Gresham College - lectures on widely ranging topics, presented by professors but targetting the layperson
• The Morbid Zoo - A cool gal doing analysis of movies, usually horror, but sometimes others, with an eye toward ideology and culture (Hellraiser, Smile, Twilight, PotC, etc.)
• Folding Ideas - More film analysis, but with a tack toward various criticisms
• Doctor Who - the old series are all on the tubes now. Not educational, but fun.

Red letter media

I love Star Trek, but don't want to watch the modern Alex kurtzman garbage, so they take the bullet for me.

I'm also not a movie guy, so watching their reviews/analysis while playing Minecraft is more entertaining than the movies they talk about.

Best of the worst is them watching B and direct to video movies that i wouldn't otherwise know about.

Well ... My go-to is still Hbomberguy. Eben if I don't know/care about the topic I know every vid of bis will be interesting and worth the time investment. The jokes are really funny (even on rewatches) and I've learned a lot. I watch old Hbomb videos to Fall asleep to almost every night.

Main issue: there's one video every 1-2 years ... However if you've never seen one you'll have the back log to get through.

Haven’t seen Philosophy Tube on here yet.

High quality and engaging deep dives on various philosophy-related topics. Abigail, the face of the channel is an actor and playwright (and an academic) and that very much shines through.

I love Technology Connections for an easy, interesting watch. He just explains how appliances work lol

Peter Dibble has some great documentaries on historical curiosities around the Pacific Northwest, and beyond.

Technology Connections does deep dives into topics of technology, specific devices and appliances, and generally is very entertaining and informative.

RedLetterMedia for film critiques, so bad it’s good reviews, and comedy.

Defunctland does documentaries around theme parks.

Tasting History with Max Miller is a very educational historical food dishes show. Not super long form.

Matt Baume does great “LGBTQ+ in TV, historically” type of content. And wrote a book about it which is great too.

Stand-up Maths does great math content. Yeah, it’s math, but it’s fun. Bonus is he also wrote a great book relating to his content about engineering and maths mistakes in real life on large scales.

LGR- retro computer tech

Techmoan- retro audio tech

For educative scientific YT channels I'd recommend Veritasium, The Action Lab and NileRed to name a few. They produce top quality scientific videos about really interesting phenomenas and experiments. And the best part is they make the concepts simple to understand without the need of a degree or smth lol

Depends how long is long form for you, if you mean like multi hour videos I have less to give. But for like 25 to 40 minutes videos:

Practical engineering - educational videos about civil engineering.

Dr. Becky - space/astronomy news from an astrophysicist.

Plainly difficult - civil disaster documentaries

Joseph Anderson - gaming essays (multi hour)

Raycevick - gaming essays (around 30min)

The sphere hunter - game essays, mainly classic horror

Jay Foreman - British comedy.

LGR - retro tech deep dives, and tech oddware.

Joe Scott - Did you know, style investigations.

Plus some already mentioned. There is probably more, but keeping this shorter.

For long form,

Bobby Broccoli, ~1hr videos on science scandals https://youtube.com/@bobbybroccoli

Defunctland, 30m to 1h45m videos on defunct theme parks and rides https://youtube.com/@defunctland

Your dinosaurs are wrong, 15m to 1h45m videos on comparing toy dinosaurs to the most up to date research https://youtube.com/@yourdinosaursarewrong

2nd on Drachinifel, 7m to 1h45m videos on naval History https://youtube.com/@drachinifel

Perun, 1h videos on defense economics https://youtube.com/@perunau

Diplo Strats, 2h to 6h videos on diplomacy the board game, like risk on massive steroids https://youtube.com/@diplostrats

A Catholic socialist, a Jewish anarchist, and a Muslim communist walk into a bar, and they make a podcast about engineering disasters: Well There's Your Problem. It's great for that intersection of people for whom the phrase "crimes against TERFs aren't crimes" resonates and like listening to an engineer complain about low quality as-builts 2 hours into a 3 hour episode about 9/11

I was sold on the show when I found out that the episode about the Titanic was split into two parts, totaling around 5 and 1/2 hours. That's partially because they spend a lot of time bullshitting, and partially because they go really in-depth about how and why structures fail

Contrapoints is one of the youtube GOATs for a reason. High production values, thought provoking content, and a level of thought and honesty that's powerful. Her video that's absolutely definitely about twilight and nothing else caused days of discussion with my wife.

Folding Ideas is a documentarian with a film background. He's most famous for his videos about NFTs and meme stocks, but all his videos are excellent. "I don't know James Rolfe" was a youtube filmmaker descending into madness attempting to understand another one.

Philosophy Tube is a woman who got pissed that the UK was raising tuitions so she committed to giving away the knowledge she got in her philosophy degree. Sometimes she plays with clickbait, but in a very self aware way. Her content is definitely meant to make you think

Hbomberguy is a man who made a 4 hour video about youtube plagiarism so popular the Onion referenced it. He's largely a video game critic but does some deep dives into political topics like climate denial, flat earth, and antivax

Sarah Z is a older gen z media and fandom critic who largely leans towards Tumblr oriented topics. She consistently has good takes. I really liked her video on how the internet talks about narcissists that I watched over the weekend.

Strange Aeons is probably my suggestion people are least likely to like. She's like if Sarah Z was a lot weirder. You want someone to explain the omegaverse or Snapewives or the other bizarre outlets of fandom in a wat that's generally respectful to them? She's got you. In particular I like how she's respectful towards weirdness when it's not harmful and that she treats trolls as the performance artists they can be.

Practical engineering is youtube for the sort of people who think bridges can be interesting. He's a civil engineer with a fair bit of charisma talking about civil engineering.

Stuff made here is for when you want impractical engineering. He's a dork who designs and builds weird shit for its own sake.

Defunctland, listen I'm not really into amusement parks that much, but this guy makes them fascinating to hear about.

Steve Wallis - Calm Canadian dude that does stealth camping, he'll just camp behind a McDonald's billboard and is very chill about it

Folding Ideas is a favorite of mine.

Coffeezilla for crypto exposes

Brick immortar- probably the single most technical long form YT channel in the engineering disasters category

NNKH - fixing things that probably shouldn't be bothered with.

Green dot aviation - air disasters and near disasters

Pilot debrief - light aviation crash analysis

Andrew camarata - long, long form time lapse videos of running backhoes and dozers to cut roads and things, nice to relax to.

The great war - I watch on nebula but I think they are on YT too.

Hoog - explainers

Bald and bankrupt - I've heard mixed things about the guy as a person but his videos are entertaining, in the "travel to unusual places" genre

Integza - another one on nebula but I think also on YT. Building rocket engines with 3d printers, etc

Driving 4 answers - probably the single best automotive focused engineering channel

Ahoy @xboxahoy. Very well produced videos about gaming. A brief history of graphics, iconic arms, video game origins and more.

who do you recommend I follow?

What I like may not be what you like at all. I mean, depends on your interests.

And I don't "follow" any of these, watch every thing when it comes out. These are just some YouTubers for whom I've had a high proportion of their material wind up being something that I feel is worth watching.

Montemayor

Does military history, mostly naval. Does not put out a lot of videos, but from the ones that I do follow, has really done his research through the written material out there before putting the material out, does a good job of highlighting what's important.

To a lesser degree, Drachinifel and The Operations Room. They're also military history, but I don't feel like they do as much research or highlight the important bits as well. Drachinifel focuses more on surface gun-era naval warfare, and The Operations Room tends to deal with newer stuff.

The Slow Mo Guys. Not exactly deep stuff, but they do one thing: high-quality interesting slow-motion footage. Pretty popular, so you may have heard of them before. I think it might be interesting to have some sort of analogous channel that does videos of microscope stuff, pans around something with a nice microscope.

SmarterEveryDay does, I think, a good job of explaining interesting things in our daily world from an engineering/technical standpoint; guy does a good job of researching his material. You'll probably walk away from this knowing this that you didn't.

CGPGrey does stick-figure illustrated things that also highlight interesting stuff, often relating to legal or political or historical stuff.

Perun does defense economics, and has had interesting and informed material on the Russo-Ukrainian War. Michael Kofman, an analyst who focuses on the Russian military, doesn't have a YouTube channel, but many YouTube channels do interview him, and while he's kind of dry, I also think that his material on Ukraine is pretty worthwhile -- he's consistently avoided alarmist stuff or cheerleading over the course of the war. Can find material with him via searching for his name.

One of the problems I have with YouTube is a side effect of the fact that it pays content creators. I don't have any real problem with that per se -- I mean, sure, you wanna do work and get paid, that's fine. The problem is that there's no real "YouTube of articles". The result is that a lot of content creators out there are putting stuff in video form that really doesn't need to be in video form, just because they want some reasonable way to monetize it. The above videos are from people who generally take advantage of the video format (well, Michael Kofman could really do just fine on a podcast and often does, but aside from that). I've seen too many YouTube videos -- including those being submitted on the Threadiverse -- that would really be better as text and possibly image articles.

EDIT: Oh, right. Someone else mentioned Primitive Technology, which I would definitely second. Has a guy go out in the woods with just his shorts and basically manufacture a lot of basic technology from the ground up. Does have subtitles, but no narration or speech. The practical use of what he does is probably limited, but I found it fascinating. I remember that this was very popular for a while on Reddit.

Buckin Billy Ray - interesting videos about cutting trees down and servicing chainsaws. A little bit unchained (excuse the pun) in a wholesome way as he seems to randomly intersperse his videos with positive affirmations like 'be kind' 'love your friends' which is kind of wholesome

Way out west - an older English guy living in the West of Ireland making things like a railway for transporting garlic

I did a thing - a hilariously unhinged aussie bloke

James Hoffman - for coffee. And hames joffman also

Karl Rock - travels around India/Pakistan exploring the places

Mike okay - travels to really off the beaten track places like Iraq.

Maximus ironthumper - many videos, the project kermit series is him rebuilding a land rover defender from scratch

Still it - distilling and making spirits

I saw a lot of tech and science channel in the comments so to balance that out, here are some of my favourite crafting channels:

North of the border: creates a clay sculpture every week. Generally it is something nerdy or something cursed

Enchanterium: repaint dolls, often to popular characters. They also sew their own outfits. A lot of fun even if you're not interested in dolls

Nerdforge: create a lot of crazy projects, mostly related to nerdy stuff. (Last project was a 2m booknook)

Wicked makers: create decorations and animatronics for Halloween

Florian Gadsby: very talented potter with very relaxing voice and videos

Pottery to the people: pottery videos, often trying new experiments

Evan and Katelyn: videos on stuff that they build. Always a lot of fun (last video: how they built an ergonomic laptop)

TL Yarn Crafts: crochet videos

Kaypea Creations: making of art dolls (animals), either out of clay or fake fur.

Studson Studios: creates amazing sculptures out of mostly trash. Amazing channel, one of my favourites

Make strange things: makes strange things. Small channel but greatly appreciated

Boylei hobby time: creates dioramas

Lightning cosplay: creats amazing cosplays

Transcended furniture gallery: restores vintage furniture

Bonus: Half-Asleep Chris: videos with stop motion elements, mostly about cats and/or lego

My #1 go to is probably Cathode Ray Dude. He makes videos mostly on old tech which is what I'm very interested in.

If you're more looking for exposing scandals there's always Coffeezilla/Voidzill.

No wonder I feel like such an outsider here. I've been on youtube for almost two decades and there's not a single channel I follow mentioned here in this thread.

EDIT: Well there was one match: Primitive Technology

Because I manually download videos to watch on the bus or train (thanks Grayjay & NewPipe), most of my subscriptions are for long-form, often listenable content:

Retro Tech: Techmoan, Technology Connections, Posy, Janus Cycle, CRD, Ben Eater, DiodeGoneWild, pannenkoek2012, videolabguy, Adrian's Digital Basement,The Science Elf, previously LGR and 8-Bit Guy/Keys

Science: Kuvina Saydaki, BobbyBroccoli, Numberphile, Computerphile, carykh

Tech News & Discussion (not always long-form): Louis Rossmann, Mental Outlaw, Brodie Robertson, SomeOrdinaryGamers, Asianometry, Atomic Shrimp, previously Thunderf00t

Urbanism: Not Just Bikes, Adam Something, Alan Fisher, Tramly, BritMonkey

D&D Story Narration: CritCrab, Puffin Forest

Bold channels are most underrated imo

Epimetheus. High quality history videos on past and current civilizations. His hand drawn art is amazing too, he tries to stay very historically accurate. No theatrical narration, just a broad view of history. My favorite channel by far.

Dr Becky. Very very good science communication on astronomy and cosmology. She always sources the papers she mentions and excels at making you understand basic astrophysics. Best explanations of a very hard topic.

Angela Collier, another science communication more focused on physics and the epistemology of the field. I love her personal perspective on all the drama in physics (e.g. why Feinman is overhyped, why it’s still such a terribly sexist field etc.) though she makes it clear that it’s her channel and her opinions. Much more detailed explanations of physics but a little harder to understand.

City Nerd data driven showcase on why cars are bad for cities, usually in a top 10 of cities ranked by some metric of transportation.

in addition to a lot of others already mentioned (there's a lot of overlap)

History:

• Step Back History

culture/politics:

• Shanspeare
• FD Signifier

writing/education:

• Zoe Bee

media/ect:

• Tale Foundry (technically about writing fiction, but they also discuss media in general along with its themes, character archetypes, ect. it's more interesting than it sounds)

• Pop Culture Detective

• Jacob Geller (mostly video games)

• My Little Thought Tree (also psychology)

• Broey Deschanel

These are channels I follow or at least like enough to look up once in a while. They're a bit random. I apologize if any are repeats, but they're worth repeating (and I didn't read every reply):

Adam Savage's tested: https://youtube.com/@tested
bigclivedotcom: https://youtube.com/@bigclivedotcom
Intelligence Squared: https://youtube.com/@intelligence-squared
MIT Open CourseWare: https://youtube.com/@mitocw
Townsends: https://youtube.com/@townsends

Entertainment:
Cirque du Soleil: https://youtube.com/@cirquedusoleil

Very other:
SBSK: https://youtube.com/@specialbooksbyspecialkids
the channel features a man who goes around and interacts with/interviews disabled children and adults. I take this one in small doses. It is not long form in the traditional sense of a well researched and thoroughly laid out topic, but I find it very wholesome/heartbreaking at the same time.

I made this spreadsheet a while back for easy sharing. Some have been mentioned like F.D Signifier and HBomberGuy. Also like Mr. Beat for history, Nth Review for games, Astrum for space, and Maritime Horrors for... maritime horrors.

Jenny Nickelson does.. nerd stuff? Highlights include:

"Church cinimatic universe" where she becomes a sommelier of art and walks you through a decade or so of some church in Canada's Easter plays, which are delightfully technical and imaginative while also being a beautiful form of cringe.

And a 4+ hour documentary/review/commentary on her visit to the short lived "star wars hotel"

I'm not big into star wars or Disneyworld/land wherever it was, but I watched that whole thing.

One I haven't seen mentioned yet that I think needs more exposure is miniminuteman: https://m.youtube.com/@miniminuteman773/

He does a mix of long form archeology videos and short form pseudo-archeology debunking. Some of it should be dry content but his delivery bridges the gap every time. He has a side channel where he posts about his side projects like his solo motorcycle trips that's also interesting.

I really like my weekly hour long defense/economics powerpoint from Perun.
