Stop comparing it to reddit. Reddit is a for-profit company with 2000 employees and a centralized system that can gives them the benefit of economies and efficiencies of scale.
The Fediverse is a decentralized system. Decentralized systems are not made to be efficient, they are made to be robust and resilient. The different nodes are meant to be doing more work overall, but that is okay because it means that even if one of the nodes is overloaded or faulty, the system as a whole continues to function.
The more you argue that we should even compare lemmy.world (or anyone else in the fediverse) with reddit, the more concerned I get that the mods and admins there don’t get the point of decentralization.
