@tsarstepan,
I take your points. There is this gal I love that has taught me so much about keto in the practical everyday sense. Most of her videos are a delight to watch. What I love most about her is that she is just such a normal, day to day person. She is entertaining and knows how to hold your interest in the subject, but not in an over the top way. She and others like her can be a rarity.
I think it's hard for some people to find the balance between holding your audiences attention, not making it all about yourself (like particularly teenage girls tend to do, although I get that's where they are in life, in their bubble), keeping on track with only small occassional diversions that don't take away from the purpose of your video.
I get appreciating the person who can point out the smallest flaws, if the subject is one that's important to you, and you are a connoisseur of that area. It's lovely to have those small things presented.
The example I'm giving below is a step up from the "I'm sitting alone in front of the camera. I have a message. I want to give it in a way that holds my audiences attention."
I decided I wanted to learn how to make sauerkraut. Looking around, many of the videos are dry as bones, doesn't address some weird thing that does crop up, assumes you are already knowledgeable about the subject, etc.
Then I found Brad.
Ok, he and Vinnie do edit the videos to make them more entertaining, funny. That's what makes you pay attention to him, and the process. Not everyone can make fermented foods entertaining. That's why Brad (and the invisible Vinnie) are so great. The thing is, things more along smartly even though he's fooling around.
After watching, and rewatching certain bits as I tackled this task, I felt so much more confident than watching others that were as unstimulating as you would expect the subject of saurkraut to be.
