The biggest surprise for me was the https://hexbear.net count, an instance I hardly interact with.

Lemmy.world has no lock in on their "power". They have the most volunteer labor, money, and infrastructure. That's makes them stable, so people aren't worried about their data suddenly going offline (like kbin) and they don't worry about the service being flaky.
The same can be said about gmail and it is the same kind of problem here. Yes lemmy.world is not a profit orient it giant, but it is still a problem when one actor has this power over a federated network. (the scale of the problem is of course a lot larger with gmail)
Technical issues with Lemmy are, I think, still driving people to larger instances.
The big one is that if I make a community on a smaller instance, and gain ANY amount of volume and traction (which is not all that easy to do in the first place) and that server vanishes, shit's just... dead. It's gone and not coming back, because you can't move a community from a dead server to a live server.
Which means using one of the big, established, funded, stable, working instances is the only rational choice, but that also means I'll probably just make an account and post exclusively from there, and thus you end up in this cycle of everyone just going to one of the larger instances in preference to any of the smaller ones.
Everyone goes on and on and on about account portability being very important (which, I suppose it is: I don't think we need account portability but rather distributed identity independent of the specific platform you're using, but that's a whole different technical mess) but for something like Lemmy, being assured that the community you're working on will survive servers vanishing and a means to "take ownership" in a way that lets you port it to another home if and when your instance dies - because, for the most part, it's going to at some point - is far far more needed.
The size difference between Lemmy.world and lemm.ee could still be improved
