Oh! I just realized I have something to add to this.
Sort of tangential, but there's also a site called livecoding.tv, which is like Twitch, but for programmers and such.
I'm not sure which channels to follow specifically, but some of them are nice and concise, while others are long and drawn out. Like the difference between someone who prepared a scripted live tutorial vs. someone with an amateur vlogging channel.
If you check it out, let me know if you've found any good channels to follow.
