Steemit is A, it’s a regularly centralized website with global admins, claiming to be “decentralized” simply because it’s built on a blockchain. Whenever you are asking yourself whether something is “decentralized” or not, ask “how can I run a full node”? “What are the hardware requirements”? Steemit admins won’t answer those questions. Whereas you can easily spin up your own ActivityPub (Mastodon or Lemmy) instance (even though those instances work like regularly centralized websites, at least you have the option to run your own).

On Plebbit, just using the desktop app of a client (like Seedit’s desktop app you can download here means you are running a full node already. The app runs an IPFS node in the background, seeding all content you browse automatically, thereby improving the speed of the network for everybody else. The more nodes there are, the more decentralized the network is, so if all users can easily run a node and are incentivized to do so, then the network is properly decentralized/distributed. On Seedit, you can’t run a community if you don’t run a full node (the community is the node, acting like a server, and users connect to it P2P). There are no global admins.

worse content searching

It’s pure p2p so it can’t have content searching straight out of the box, but it can easily have indexes like 4chan archivers to search in known subplebbits. It’s entirely possible to crawl all active subplebbits and archive them all in a central database, and use that for search. This will happen, and plebbit clients will probably implement multiple such archivers to run search in them. And search engines will be able to index.

worse scalability

It’s orders of magnitude better scalability than regular sites such as federated instances. Because it works like torrents, except you always seed, so plebbit nodes will inevitably improve the network speed more and more as more nodes join. And running a node works on a rasp pi. And all content is just text (including links from which media is embedded by the clients), so there’s no scalability issue relatively to storage, either.

worse moderation

It has way better moderation, because it’s just like reddit in that every community moderates itself, except there’s no global admins able to censor a community/node or impose global rules. Plebbit clients are simply static HTML tools to browse the p2p network to connect to each community directly. Every community is incentivized to moderate itself effectively, or they become unusable, and to enter the homepages of the clients they must get voted for by holders of the plebbit token, via a gasless governance system using pubsub it’s this page, you’ll be able to vote for communities, i.e. downvote communities that aren’t well moderated to remove them from the homepage for everyone). Right now, this homepage default list is centrally controlled by the developers, it’s the only remaining centralized part of the project.

You smell like you didn’t wash yourself for 20 days

Also Mastodon is based on ActivityPub
