Oh man, I hope this server can maintain. Support if you can. There is no CEO but there is a server admin who has to pay for us to be on it. No centralization means its up to us to keep it going. I don't know the history of lemmy world and I'd hate to see it go because it was too expensive for it's popularity. Something to think about.
It's run by the same guy who runs mastodon.world (Ruud) so he has experience with huge servers. Apparently this server is currently set up to handle a million users. Here's the Patreon: https://www.patreon.com/mastodonworld
