Is it so you don't lose the idea? Is it related to you always trying to work as quickly as possible? Is it because of YouTube's algorithm?
none of those. the reason is because videos take way way too long to make, and therefore they are not able to be released at a pace in any way commensurate with humane viewing habits. it's kind of like when a restaurant takes 10 weeks to make a meal. would be kind of a useless restaurant, in that case, would you agree
