(#6)Yes, but isn't blue bird (I refuse to call it X) much worse? It's full of raging people and arguments as far as I know. Either way even if you just look at ST's page it doesn't help because everything you click leads you to a login popup, and I don't want to make an account on that trash terrible social media (my opinion) and they don't really update it on stuff like downtimes or reasons.
Considering that the Bluesky Terms of Service state that you must be 13 or older to make an account, I don't think the people who use Bluesky are the ones to which the Scratch Team is aiming to advertise their website. I know you suggest that teachers and parents could see this sort of message, but unless I'm just unfamiliar with how Bluesky works, I'm not convinced that this would be effective; I feel like people who view/follow official Scratch Team posts would be the people who are already interested in, using, or working with Scratch. So at this point it is mainly a question of how educators find Scratch in the first place; and something tells me it's not just by viewing posts on X.
I don't know how much more this one will help though.
