I feel like this is how it will realistically happen though. People will flock to one instance and use that one community, otherwise it becomes too stagnated.
The best thing about federation is that if that hugely popular community’s instance were to crash/go down, the community can just join another one. Sure it might take some coordination, but why not have one central place to hang out until it gets shitty?
Imagine youre at your favorite bar. They get new owners and then all their prices change. But hey guess what, you can make an exact copy of the same bar on a different instance! “Hey guys, lets all go to this new bar thats literally the same thing across the street!” and then everybody is happy.
Give it time. People who are joining lemmy/kbin for the first time are incredibly interested in disussing this particular topic. I think by the end of July, we’ll truly start to see this community take shape.
