The user experience is quite different though?

And I think there’s value in decentralization even without the granularity of a server-per-person. Sure, some Mastodon servers might go down, or some admins might do unwise things, but damage should be limited. the entire network - I hope - would not fail.

Of course, I’ve lived through the death of Usenet, so perhaps I should not be so optimistic :-/

Edit: not to mention the arguable centralization of email, blogging, and perhaps soon podcasting :-(
