Maybe for this crowd. Almost no services I use aside from email were federated, before I went to Lemmy and Mastodon. And now it’s email, Lemmy, and Mastodon. Average users just chasing a good experience don’t really care about federation, despite its benefits.

The public servers that are just operating on discovery - sure. I have a private Discord with friends I’ll be looking to transfer, as well as a community with external intake sources.

Revolt is pretty good! Most of the features you want from discord are already there. It’s FOSS and servers can be self-hosted.
