If you want your channel to be successful in the long term, then maintain a continuum in your video releases.
Don't jump from topic to topic... If you start a repair or a topic, expound and elaborate on it in a continuous series of videos... 8-bit guy is an example of what not to do (I am picking on 8-bit guy but I actually have no real issues with him)... From repairing hardware, to videos on packaging his software, to a new computer release (Commander X16), solar panels, opening a new arcade... What is this, a retro channel, or a mid-life crisis spending spree supported by the donations on Patreon from the unwashed masses?
Going off on a tangent is welcome once in a while, but when your entire channel becomes a series of tangents, you have lost focus. I'm not saying it's easy, you have to stay fresh, but for example, couldn't 8-bit guy show us a bit more how he does all his programming? He spoke of pathfinding in his new game -- how about going into it with a bit more detail? the modern Warcraft 2 hacked russian release has "improved" pathfinding... Maybe juxtapose that with your implementation?
Or... do whatever you want -- after all, we do watch your videos for free, you're free to do as you please.
