After doing a few coaching sessions for my www.teachingyouhowtolearn.com project, it has become clear that I really need to write some Obsidian guides for the site.
For the time being, I've made this "Quick Obsidian Guide" post, where I outline some key features, why Obsidian > Roam Research, and a quick screenshare video where I show my vault and show some key features.
My learning workflow is pretty much just Anki + Obsidian, and I highly recommend Obsidian to everyone. It's free too so there's no risk in trying it out!
P.S. I'm still offering free 1:1 learning coaching, see this page for details :)
