After Elon Musk's acquisition of Twitter, many scientists report the platform is no longer suitable for professional use. A recent survey indicates that researchers are increasingly turning to Bluesky, which they view as more useful, welcoming, and aligned with their goals.
X is a right-wing propaganda platform now. Bluesky is not a good alternative though. It’s just as controlled and toxic as X was just before Elan bought it and will eventually become what X is now when a major corporation or rich person decides to grab it or it goes public. The federation functionality is just for show and marketing. I wish people would stop just jumping when platforms become truly horrible and then jumping to something that will be made as horrible very easily after it becomes popular enough.
