You and I will have to agree to disagree on this. Yes, active users continues to grow - on already dominant platforms. And by that I mean KBin.social as a platform, not all KBin instances; or Mastodon.Social, or even Lemmy.ML. Yes, there's not a singularity yet, but even this limited plurality shows that it's a pain in the neck to deal with the Fediverse as a whole, so pick your local poison and go for it.
