Thank you for putting all of this so succintly. I’m not into teaching, but I’ve done a few workshops and I always struggle to express the attitude you described to get the pupils engaged.
I had this same attitude when I was a student. Even though my professors were older and more knowledgable, I always tried to approach them as peers and it worked out great. I’m not the sharpest tool in the shed, but because I talked, I could use my strengths better because I was more aware of the expectations and requirements than a portion of other students.
Tbh, I don’t think there is a definite “youtube style” that describes all content on youtube. There are some similarities and within categories of videos you can find styles that are more popular within that category, but site wide I would say it provides quite a bit of variety.
What could be called youtube style is that it’s not TV. In that sense YT style and TV style maybe make some sense.
