Per Shiffman and Wester, an “overwhelming majority” of respondents mentioned that Bluesky has a “vibrant and wholesome on-line science group,” whereas Twitter not does. And plenty of Bluesky customers reported getting extra bang for his or her buck, so to talk, on Bluesky. They may have a decrease follower rely, however these followers are much more engaged: Somebody with 50,000 Twitter/X followers, for instance, may get 5 likes on a given publish; however on Bluesky, they could solely have 5,000 followers, however their posts will get 100 likes.
Based on Shiffman, Twitter all the time was once within the prime three by way of referral site visitors for posts on Southern Fried Science. Then got here the “Muskification,” and immediately Twitter referrals weren’t even cracking the highest 10. Against this, in 2025 up to now, Bluesky has pushed “100 instances as many web page views” to Southern Fried Science as Twitter. Paradoxically, “the weblog publish that’s gotten essentially the most web page views from Twitter is the one about this paper,” mentioned Shiffman.
Ars social media supervisor Connor McInerney confirmed that Ars Technica has additionally seen a gradual dip in Twitter referral site visitors up to now in 2025. Moreover, “I can say anecdotally that over the summer season we’ve seen our Bluesky site visitors begin to surpass our Twitter site visitors for the primary time,” McInerney mentioned, attributing the expansion to a mix of things. “We’ve been posting to the platform extra typically and our viewers there has grown considerably. By my estimate our viewers has grown by 63 % since January. The platform basically has grown loads too—that they had 10 million customers in September of final yr, and this month the newest numbers point out they’re at 38 million customers. Conversely, our Twitter viewers has remained pretty static throughout the identical time frame.”
Bubble, Schmubble
As for scientists seeking to share scholarly papers on-line, Shiffman pulled the Altmetrics stats for his and Wester’s new paper. “It’s already one of many 10 most shared papers within the historical past of that journal on social media,” he mentioned, with 14 shares on Twitter/X vs over a thousand shares on Bluesky (as of 4 pm ET on August 20). “If the purpose is exhibiting there’s a extra energetic tutorial scholarly dialog on Bluesky—I imply, rattling,” he mentioned.
And whereas there was a gradual drumbeat of op-eds of late in sure legacy media shops accusing Bluesky of being trapped in its personal liberal bubble, Shiffman, for one, has few issues about that. “I don’t care about this, as a result of I don’t use social media to argue with strangers about politics,” he wrote in his accompanying weblog publish. “I exploit social media to speak about fish. Once I speak about fish on Bluesky, folks ask me questions on fish. Once I speak about fish on Twitter, folks threaten to homicide my household as a result of we’re Jewish.” He in contrast the present incarnation of Twitter as no higher than 4Chan or TruthSocial by way of the share of “conspiracy-prone extremists” within the viewers. “Even if you wish to keep, the algorithm is working in opposition to you,” he wrote.
“There have been a whole lot of opinion items about why Bluesky will not be helpful as a result of the folks there are typically comparatively left-leaning,” Shiffman advised Ars. “I haven’t seen any of those self same folks say that Twitter is dangerous as a result of it’s comparatively right-leaning. Twitter will not be a consultant pattern of the general public both.” And given his deal with ocean conservation and science-based, data-driven environmental advocacy, he’s more likely to discover a extra engaged and persuadable viewers at Bluesky.
