Even within Mastodon it’s a mess with all the various servers. It’s too confusing.
I know people like to compare it with email, but with email I’m sending from server A to server B, I’m not sending from server A to hundreds of other servers and seeing that it doesn’t always make it everywhere. And if I edit or delete a post, maybe those changes will propagate out, but maybe not. Conceptually it’s hard, but even as a user who doesn’t care as long as the magic works… the magic doesn’t work all that well. So where does that leave decentralized social media?
Bring back blogs + rss as the norm. It makes sense, it works, the user is in control, and it never feels like it is trying to substitute for human connection.
