A study examining 2.6m Bluesky posts referencing more than 500,000 scholarly articles over the past two and a half years found they demonstrated “substantially higher levels of interaction” – likes, reposts, replies and quotes – and greater “textual originality” than previously reported for X, formerly Twitter.

A study suggests proper engagement is the key to the favour Bluesky has found among scientists. A team predominantly from the UK’s Sheffield University found that almost half the scientific posts on Bluesky received at least 10 likes, while a third were reposted 10 or more times. Previous research has shown those metrics were far lower on X, with up to 4.4% receiving 10 or more reposts.

“We had a large community on science Twitter, where I was very active for 15 years,” said Tara C Smith, a professor of epidemiology at Kent State University College of Public Health in the US. “Engagement dropped off dramatically and the number of troll and bot responses increased. It just became a useless platform to me, despite having about 130,000 followers at my peak.
“At Bluesky, though it’s significantly smaller, I can have good discussions with people who are interested in my area as well as fellow experts. It serves the same purpose as SciTwitter as far as keeping up with new research, but also is far more amenable to conversation.”

David Shiffman, a marine conservation biologist, was another early adopter of social media for science engagement. He said he switched to Bluesky after becoming concerned about conspiracy theories on X.
“Bluesky isn’t better than Twitter ever was, but it’s a hell of a lot better than Twitter is now,” he said.
Andrew Thaler, a deep sea biologist with 38,000 Bluesky followers, said: “The community is platform agnostic, they really don’t care what platform you are on. What matters is where the people are. So it was about making sure people moved over and the community continued to flourish. Science on Bluesky is kind of the best part of Bluesky. A smaller social network is not necessarily a negative. The engagement is tremendous.”
