Science weights in on the twitter migration by scientists.

"Even if academic Twitter ends up largely moving to Mastodon, the big question is whether the general public will move there, too, allowing scientists to communicate with more than just each other. “When I tweet, I’m talking to my neighbor and the person in the grocery store and the teenager who is thinking about studying science in college,” Fiesler says. “That’s the beauty of scientists on social media"
#fediverse has grown and will continue to expand on interest networks converging. The general members of the public will arrive, on the heels of journalists who cover stories. That phenomenon already happens.
Yes, true.
When I started using twitter (2006), no one cared much about these things. We used to share status updates, and that was about it. Then others arrived shared papers and notes, and all of that.
This is the bit I like about qoto.org. We can share papers, codes, and discuss about it. Like arXiv, except the discussions happen at the same time as in a social medium. Qoto also because it allows $\alpha$ style posting, I think.
