@austingovella@EpiphanicSynchronicity@Colman@gelberhut@biscotty@obsidianmd I use folders where it makes sense to me to do so. Where they add value to my workflow. Some sections of my vault have folders 2 or 3 deep, because that's what I need for those topics.
I also have a folder called ALL THE NOTES (my folder names are always in capitals, for easy differentiation from files) where everything else is dumped.
Works great for me! There's no true religion for organising your stuff.
