Lemmy.world is very popular, and one of the largest instances. They do a great job with moderation. There’s a lot of positives with lemmy.world
Recently, over the last month, federation issues have become more and more drastic. Some comments from lemmy.world take days, or never, synchronize with other instances.
The current incarnation of activity pub as implemented in Lemmy has rate issues with a very popular instance. So now lemmy.world is becoming a island. This is bad because it fractures the discussion, and encourages more centralization on Lemmy.world which actually weakens the ability of the federated universe to survive a single instance failing or just turning off.
For the time being, I encourage everyone to post to communities hosted on other instances so that the conversation can be consistently access by people across the entire Fediverse. I don’t think it’s necessary to move your user account, because your client will post to the host instance of a community when you make a comment in that community I believe.

Not really though, with Lemmy the host and front end are the same. You access Lemmy from hacker talks, I access it from shitjustworks, both our respective instances host our respective data and provide us a UI to access their instance and could decide to only give us access to the content that they host as some instances already do.
What I’m talking about is front end devs not having to host any of the content themselves, just accessing the database hosted by others and showing that info in the UI they developed and pushing changes to the database when the users sign up or post comments.
Front end doesn’t have control over where the info is stored and don’t store anything locally, back end doesn’t have control over who’s pulling and pushing data, they can just choose to filter out NSFW content from their own servers but it just means it won’t pick them to host that content and will instead pick servers that don’t mind hosting it.
In this way the hosting is the same as any hosting services but completely decentralized and the data is open to all and no host can wipe it because of the backups (contrary to Lemmy where if an instance disappears all the content it hosted is gone).
So the data would be stored in something like IPFS? Or ceph?
Ceph has issues because the The metadata nodes needed for disc admission are central points of control
IPFS could work, but the cost of hosting go up exponentially. But yeah you could build Lemmy on top of IPFS
