I have tested #BlueSky for the past few weeks, for curiosity.

It's a bit like #X but you need an invitation code to join. A kind a private club.

I don't have many followers / people to follow, so it's a bit dead. Some folks are obviously cross-posting from X so there is some activity there, but quite limited.

#fediverse is still by far the best social network, no doubt !

PS: if anyone wants to test it, I have 1 invitation code (DM me). Requests from pseudo accounts will be ignored.
