Hi everyone.
I’m new to these kinds of innovative platforms, and I’ve come across Mastodon and Bluesky in particular. I’ve realized that both use different but equally free and open-source protocols, so my question is: are there any substantial differences between the two social networks? Should I choose one over the other?
Thanks for your replies, and have a great day.


The problem with Mastodon (ActivityPub) is that your identity is held hostage by your server admin. If your instance goes down or you have a disagreement with the mod, good luck moving. You can migrate followers, but you lose all your posts and history.
ATProto fixes this by decoupling your identity from the server, you can swap servers without losing anything.
Also, Bluesky has truly customizable algorithms instead of being forced into the chronological view or whatever the instance admin decided.
