Ask HN: Obsidian/Roam users: Did you get any value out of it after a few years?

Personal knowledge management tools such as Roam, Obsidian, and Notion started gaining traction a few years ago.

Now that the hype has passed, I'm contemplating whether it is worth investing my time in documenting my knowledge using these tools instead of relying on the Evernote app or pen and paper, which I lose/forget too often.

I'm genuinely curious if any users on Hacker News have consistently documented their knowledge and found value in doing so after using these tools for a few years?
