Since my last post yesterday, lemmy.world has added over 3000 new users, bringing the total user count to 22000 today (source: https://lemmy.fediverse.observer/list). It firmly holds the position of the second-largest lemmy instance, passing beehaw.org by a large margin of 10000 users.
In other news, beehaw has defederated from lemmy.world a few hours ago. How does the third-largest instance only have 4 mods admins for its 12000 users?!
So much going on!
If this stuff really catches on I predict there will be services built around setting up private instances for that purpose.
