I don’t use Instagram or tiktok, but I’m a longtime consumer of YouTube educational content, and my shorts feed mostly matches. I suspect that the presence of extremely high quality educational video on youtube allows many creators to use shorts as a gateway into their longer form videos.
In short, I think they’re all only as good as you’ve trained the algorithm to make them. Without algorithmic training, I’m sure they’re the same.
None of these creators are flawless, and you may not love their presentation style, but I discovered them all through shorts, and they have all taught me new things.
