this is 100% why I write "courses" alongside my notes when learning something- forces you to think about pitfalls you fall into while learning, things you need to revisit and an overall story on how to introduce a topic.

but blogging? Outside of an immediate personal sphere I don't really see the need. Although that said I'm looking at things like [pico.sh](https://pico.sh/prose) just to play around with presentable notes/courses rather than my default obsidian stuff.
