From a technical standpoint, the protocol (ActivityPud) underlying Lemmy and Kbin has security and performance faults that make it inefficient. It's a great step towards decentralization but there is another alternative that I want to raise awareness of: Nostr.
Nostr is another protocol, like ActivityPub. Similarly, to Lemmy and Kbin on ActivityPub, Nostr has clients built on top of it. For instance: Damus on iOS, Coracle.social on web.
Right now, most clients only behave like twitter clones. However, the nostr protocol is much more robust than ActivityPub. It could easily support reddit-like platforms-- developers are already working on it-- as well as far more, like crypto payments, game-server-host connection, and more. Critically, it is possible to create ActivityPub-Nostr bridges.
It's early days in this new frontier of decentralized social platforms. If you are excited about The Fediverse, definitely play with the nostr protocol as well.
In this thread, you can also share your nostr pub keys so we can build the GME community there!
Paying for posts, relays is better incentive alignment for users and maintainers than twitter or the fediverse
