@irfan@joesbrat67 I am also on Calckey.social because I got excited when it opened, great and small community and it is obviously a time saver having Calc run it.
I'm also on Mastodon.world and love Ruud. He runs Calckey.world and if one is optimizing for stability and don't want to self host that instance is probably pretty great.
The move though is not centralizing. The software itself runs very stable, I believe! This server just is the biggest and gets the most bleeding edge updates and probably does not have dedicated devops / auto scaling.
I intend to shift to self hosting when I have the time in my life.
