I agree. I think Kbin and Lemmy can learn a few things from how Mastodon operates right now... Very easy to sign up (though there's still the weird barrier to entry of figuring out which instance to sign up for), and then you're exposed to the entire federated Mastodon content pretty transparently.

By contrast, on Lemmy, you have to select "All" to see all communities across servers. And Kbin doesn't currently see federated content at all, so...

And then, ultimately, you're stuck with a new problem that the Fediverse is creating : if I want to subscribe, say, to a gaming community/magazine, which one do I pick? Every instance has its own communities on popular topics.
