Most people access the Fediverse through one of the large instances: lemmy.world, kbin, or beehaw. New or small instances of Lemmy have no content by default, and can most easily get content by linking to larger Lemmy instances. This is done manually one “Community” at a time (I spent 15 minutes doing this yesterday). Meanwhile, on larger instances, content naturally aggregates as a result of the sheer number of users. Because people generally want a user experience similar to Reddit, I think it’s inevitable that most user activity will be concentrated in one or two instances. It is probable that these instances follow in the footsteps of Reddit- the cycle repeats.
I actually think the Fediverse is in the beginning the process of fragmenting into siloed smaller, centralized instances. Beehaw, which is on the list of top instances, just blacklisted everyone from lemmy.world. Each of the three largest instances now are working to be a standalone replacement for Reddit and are in direct competition with each other. It is possible that this fragmentation and instability? of Lemmy instances will kill the viability of Federated Reddit altogether, but hopefully not.
These are my main takeaways from my three days on the Fediverse. I will stick around to see if the Fediverse can sustain itself after the end of the Reddit blackouts.
I think the way Lemmy federation works is kinda perfect and I feel like things will mostly sort themselves out after a while. Like, I can foresee large and small islands of federated servers, and while that might not seem good at first, I think it can work.
For example, I might have two Fediverse users, one I use in the “mainstream” island, and another I use in not-mainstream servers that has more controversial topics. A kid might have a user in a kids appropriate island where there is no federation with servers containing adult content.
Maybe a Lemmy client can then combine content from my two users, so I can view content from the mainstream and my alt servers together.
