I've never seen this site before but wow this is going to be super helpful to new users.

I'm still learning the ins and outs of this place and the others, but part of me thought that was the feature of being federated. User accounts could seamlessly transfer from one instance to another.
Looking further into it, it looks like that feature exists for content, but not so much for accounts.
One thing I'm wondering about is how people moving from Reddit to one of these Fediverse sites are going to end up finding their "home". Like, would we need some sort of sharing bot to work between here, sysadmin@lemmy.world, sysadmin@sh.itjust.works, etc. or are we going to end up in a situation where they're all fragmented from one another?
The thing that helps Kbin the most is that it is, by far, the easiest to understand. Googling "Lemmy fediverse" gives a bunch of various links to other Lemmy instances, which are presented in a way as if they are separated from one another. Kbin appears as one site, one location for content aggregation. Although that "goes against the idea" of decentralization, most users are currently looking for their "one home to replace their old one home". The more users flock to one area and learn how it works, the more things will begin to take their proper shape, so to speak.
You can absolutely start a community about rabbits. I don't think that would count as "going off the deep end" at all. I think Reddit having its large, singular community for certain things ended up dissuading a lot of people from making communities based around things they enjoy.
The vibe I've been getting while here is that things are a lot more open. You can create a community that already exists, even with the same name, the only caveat being they cannot be located on the same instance. While I can see that possibly leading to a bit of fragmenting of some communities, It'll let people create their own little pocket of the internet and have it exactly how they want it.
Either way, you should absolutely 100% make that community!
