This server isn’t the only one I’m running in the Fediverse :-) I’m currently running these:

https://lemmy.world: You’re looking at it.

https://mastodon.world: My largest server, over 160.000 users.

https://musicworld.social: Another Mastodon server about 1 of my hobbies

https://pool.social: Another Mastodon server about another hobby of mine

https://fotofed.nl: A Pixelfed instance

https://calckey.world: A Calckey server. A bit different from Mastodon.

https://fediland.nl: A Misskey server. Calckey is forked from Misskey, personally I like calckey better.

https://play-my.video: A Peertube server

https://akkoma.nl: An Akkoma server (kind of lightweight but fully featured Mastodon)

https://ruud.social: Akkoma server just for me

https://blog.mastodon.world: My writefreely server, yes that federates too.

More to come probably…
