I write about social networks (beyond just fediverse stuff) more broadly at my personal website, which is where I first published this story about Bluesky (https://laurenshof.online/bluesky-has-3-million-accounts-invites-going-away-soon/ ). I sometimes include stories and coverage from beyond the fediverse in the weekly Fediverse Report when I feel that it has direct impact on the fediverse.
Bluesky saying they'll remove the invite system soon is one of those cases, so thats why I included it in this weeks update
