I guess the difference between PKMS and KMS to me is primarily who's using it. So yes? 😆
I would say that counts! Is there anything specific you're curious about? Particular issues in your personal system or interesting things you've seen from others?
Oh gosh, I really wish I had a proper PKMS back when I was at university. I would have done exponentially better, I'm excited for you 😆
What are folks using PKMS for?
I recently used linked thinking in Obsidian to do some critical meme analysis for therapy. It was a good exercise in creating index notes, e.g. a meme crossing over Marvel and The Good Place wouldn't fit in a folder for either one.
