A new study in Integrative and Comparative Biology reveals that a significant number of scientists are abandoning X (formerly Twitter) due to its declining professional value and migrating to Bluesky. Based on a survey of over 800 researchers and science communicators, the study documents a sharp decrease in the usefulness of X for networking, outreach, and staying current with research since its acquisition by Elon Musk. Respondents cited a rise in misinformation, spam, and extremist content as key reasons for their departure. In contrast, Bluesky is emerging as the preferred alternative, with users finding it more effective for professional engagement, appreciating its stronger moderation, and greater user control over content feeds. While the migration is clear, questions remain about Bluesky's ability to foster the diverse, grassroots movements that once thrived on X.
Scientists' Social Media Shift: From X to Bluesky
The Great Migration: A study surveying 813 scientists and communicators found a major shift away from X (formerly Twitter) towards Bluesky for professional purposes.
Declining Value of X: Since Elon Musk's 2022 acquisition, users report that X has become significantly less useful.
Roughly 75% of respondents said the platform is now "much less useful" for networking and science communication.
Key complaints include an increase in irrelevant content, ads, spam, extremist posts, and a loss of meaningful engagement.
Abandonment of X: Usage patterns show a clear departure from the platform.
Only 11% of respondents still actively use X.
Nearly 40% have deleted their accounts entirely, while almost half rarely use their existing accounts.
Bluesky as the New Hub: Bluesky is filling the void left by X, meeting the professional needs of the scientific community.
Over 94% of users utilize Bluesky to stay informed about research in their field.
Nearly 88% use it for professional networking.
Users praise Bluesky for better moderation, less algorithmic interference, and more control over their feeds.
Motivations for the Switch: Scientists were driven to Bluesky to escape the perceived rise in extremism on X, with many explicitly naming Elon Musk's changes as their reason for leaving. Many also joined after being invited by colleagues.
Future Uncertainties: While Bluesky is currently the preferred alternative, the study notes two key concerns:
It is unclear if the platform can support the same level of diversity and grassroots engagement for movements like #BlackBirdersWeek that originated on Twitter.
The long-term stability and momentum of Bluesky remain uncertain.
