I was pretty invested in the "tools for thought" space for a little while, but my interest cooled as I realized that I was using zettelkasten tools like Logseq to try and recreate simple folders of documents, because as it turns out that's all I really needed to begin with. I use Obsidian, because wiki links can be handy from time to time, but my notes these days are mostly just plain markdown sorted into folders by topic, and that's plenty for me.
