There is one simple reason why Bluesky is now about to lap Masto AGAIN and become the official alternative to Xchitter:
Bluesky is basically pre-MusKKKrat Twitter, but without the right-wing manipulation, WITH actual attempts at safety protection, and a desire please those not necessarily interested in immense political Battle Royals.
If it adopts a more progressive stance on sex work and porn expression without ceding ground to spammers, it may yet cook Xchitter and reduce it to Gab 2.0.
