@everton137 No, there wasn't a lot of discussion at #FediForum of the implications of and reasons for Brazilians signing up for #Bluesky instead of the ActivityPub based #fediverse.
I agree that it's not the similarities to Orkut aren't the main reason. Lula's tweet was certainly a big factor but it had already started before that. In https://privacy.thenexus.today/bluesky-atmosphere-fediverse/ I wrote
"Bluesky addresses many (although certainly not all) of the issues newcomers to the Mastodon faced in 2022, and has paid a lot of attention to onboarding and usability. So today's Bluesky is a much better Twitter alternative for most people than Mastodon of 2022 – or today's Mastodon."
and I'm planning on going in to detail on that in a follow-up post ... but, one simple example: there are no Braziliian instances listed on joinmastodon.org. https://mastodon.br-linux.org/instancias/ is useful but how is anybody supposed to find it?
