I use it, I don't write stuff outside hn comments lol. Obsidian is very cool, like onenote but more siliconvalley-ish and smarter.

I hate that I needed to install flatpack for it but that is literally my only complaint. Sadly, it can't replace a text/code editor lime sublime which is where I dumped a lot of non-note knowledge. If only sublimetext copied some of this stuff for markdown.

In school,I never, ever took notes unless threatened. I mention that to show you how even someone like me liked Obsidian.
