Users. Users produce the value, not Reddit. They create or share the content and submit comments to invoke discussion. This is what draws more users to the platform.

Reddit is a grumpy office landlord that thinks that because it's glued some shitty plastic panels to the wall to "modernize" that it can rock up to the whiteboard and pretend it's one of the creatives. They are terrible at understanding the product because the real product was built around their mediocre foundations.
