I made a serious effort to look into it, but without already knowing where I want to be it was impossible to decide which server to sign onto and it's an expensive choice to make upfront since they don't all federate with each other and even the ones that do federate are not guaranteed to not start beef with each other. That's before even getting to the fact that I can name at least 4 different protocols off the top of my head (Mastodon, Pleroma, Akkoma, Misskey) at various levels of not-entirely-incompatible with each other. I remember there being work on between-server account moving mechanisms in some state of almost-partially-working, too. Maybe things have changed now but I doubt it, everything I saw in the ecosystem just seemed to promote balkanization as a feature.

I'd love a truly decentralized model for this but fediverse isn't it, fediverse is a Hellenic League of city states where your ability to interact outside your bubble is beholden to your and their local leadership and shifting realities of protocol war jank.

If you do think my opinion is uninformed or mistaken at least know that I know many times more people who bounced off the idea for these reasons than people who actually managed to make heads or tails of this. Fwiw I don't use xitter/bsky either.
