You would think that maybe they could condense the best parts of a long video into a shorter one
Some channels do this, and I think it’s a really good use for the platform. Nerdforge is one channel that comes to mind - she has a few videos that are a 1 minute short (e.g. youtu.be/5QNIgDFq-vw) summarizing a 20 minute video (youtu.be/ZVqa7j6jG0Q)
