Per Shiffman and Wester, an “overwhelming majority” of respondents stated that Bluesky has a “vibrant and wholesome on-line science neighborhood,” whereas Twitter now 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 depend, however these followers are way 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.
In keeping with Shiffman, Twitter all the time was once within the prime three when it comes to 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 to this point, Bluesky has pushed “100 instances as many web page views” to Southern Fried Science as Twitter. Mockingly, “the weblog publish that’s gotten essentially the most web page views from Twitter is the one about this paper,” stated Shiffman.
Ars social media supervisor Connor McInerney confirmed that Ars Technica has additionally seen a gradual dip in Twitter referral site visitors to this point in 2025. Moreover, “I can say anecdotally that over the summer time we’ve seen our Bluesky site visitors begin to surpass our Twitter site visitors for the primary time,” McInerney stated, attributing the expansion to a mixture 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 generally has grown rather a lot too—that they had 10 million customers in September of final 12 months, and this month the most recent 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 trying 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 stated, with 14 shares on Twitter/X vs over a thousand shares on Bluesky (as of 4 pm ET on August 20). “If the aim is exhibiting there’s a extra lively tutorial scholarly dialog on Bluesky—I imply, rattling,” he stated.
And whereas there was a gradual drumbeat of op-eds of late in sure legacy media retailers 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 take advantage of social media to speak about fish. Once I discuss fish on Bluesky, individuals ask me questions on fish. Once I discuss fish on Twitter, individuals 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 when it comes to the share of “conspiracy-prone extremists” within the viewers. “Even if you wish to keep, the algorithm is working towards you,” he wrote.
“There have been a number of opinion items about why Bluesky just isn’t helpful as a result of the individuals there are typically comparatively left-leaning,” Shiffman informed Ars. “I haven’t seen any of those self same individuals say that Twitter is unhealthy as a result of it’s comparatively right-leaning. Twitter just isn’t a consultant pattern of the general public both.” And given his give attention to ocean conservation and science-based, data-driven environmental advocacy, he’s more likely to discover a extra engaged and persuadable viewers at Bluesky.
