It still doesn't work like bulletin boards where all users would see discussions get bumped and replies were linear. It only works if the sorting mechanism is the same for everyone and the discussion is ongoing. I could point you to discussions that are still active more than ten years after they started, where all the knowledge available on a subject is available...

Here's an example: https://www.advrider.com/f/threads/klr650-only-thread.742912/

Over 42 000 replies over 12 years on that specific model of motorcycle, that's simply impossible on a platform that doesn't work like bulletin boards do.

Bulletin boards is like having people sitting at a table and discussing a specific subject. Reddit/Lemmy is like an event with everyone scattered around the place with groups each having separate conversations, it might be a Star Trek convention, but you can't follow every conversations so the same thing keeps getting repeated again and again by different people because they don't realize someone already said the same thing.

There's a reason specialists still hang on forums and enthusiasts hang on Reddit...

Edit: The Lemmy devs even started developing my idea, but development stopped when the Exodus happened...
