I think you have found a nieche to fill. Problem is when you don’t really deep dive the topics or it is strictly educational, you might get bored if you are a somewhat technical person, that is not a great recipe for a YouTube channel. You will probably also have to remake the videos as software gets updated.
Also most viewers är linux nerds. The average person don’t spend all day at a computer at work just to go home and ‘work’ more by spending time watching a videos on how to work more. That means you should probably target companies and organizations directly with your content, that could be a hard sell if you expect to make an income.
With all that said, I like the idea and even if you only make a few videos you will probably learn alot, try it and see how you like it!
I still think these channels are very technical. Using jorgon that is completely foreign to someone just strictly using their computer to get work done. I am pretty deep into the different topics and even I had have to look up what they talk about.
