5.33pmWhere Are All the Americans? Fediverse Adoption and the Missing US Crowd
Spend enough time poking around Mastodon instances, looking at who runs the bigger ActivityPub servers, or reading about governments experimenting with decentralized social media, and a pattern starts to show up. A surprising amount of the interesting activity has happened outside the United States.
Japan, Germany, India, and even China come up again and again in the history of the fediverse. American institutions, meanwhile, have mostly watched from the sidelines while Silicon Valley platforms grew larger and more centralized.
I went looking for academic research to see whether that impression holds up. The answer is: maybe, but the research I found does not really answer the question I was asking.
Two studies from Arizona State University looked closely at migration away from Twitter. One focused on the Twitter-to-Mastodon exodus after Musk’s takeover. A later study looked at migration to Mastodon, Bluesky, and Threads at the same time. Both examined who left Twitter, why they left, what made them stay on another platform, and how the different platforms shaped user behavior.
Neither study breaks the data down by country.
The researchers were interested in behavior, not geography. So if you’re hoping for a clean chart showing “Mastodon users by nation,” you’re going to be disappointed. I was.
That missing data is worth mentioning because a lot of what gets said about international fediverse adoption, including what I’m about to say, comes from scattered reporting and institutional history rather than good comparative survey data.
Still, the scattered evidence is interesting.
Mastodon was reportedly much bigger in Japan than in most other countries for years before many Americans had heard of it. A big part of that came from Pixiv, which launched a Mastodon-based server called Pawoo not long after Mastodon itself appeared in 2016. Pawoo quickly became one of the largest individual servers on the network.
Germany’s role looks different. Its influence is less about one giant server and more about the institutional side of the project. Mastodon is developed by a German nonprofit. The German state of Schleswig-Holstein runs its own instance through the project. Germany’s Sovereign Tech Fund has also provided more than half a million euros for infrastructure work.
The European Union went a step further with EU Voice, an official Mastodon instance intended to give EU institutions an alternative to American-owned social networks. The experiment lasted a couple of years before being wound down.
India has its own chapter in the story. In 2019, nearly 20,000 Indian Twitter users temporarily moved to Mastodon during a dispute over moderation. Homegrown Mastodon-derived services such as Tooter also appeared, although Tooter became controversial over changes it had made to the underlying code.
China is a very different case. Mastodon has been used there as a way around domestic censorship. That’s not really the same phenomenon as Americans leaving Twitter because they dislike a new owner or recommendation algorithm. For some Chinese users, decentralized social media has been about access to open communication in the first place.
Australia had another kind of example. Switter was a Mastodon instance built specifically for sex workers. It eventually shut down in 2022 after legal and regulatory changes in Australia and the United States made operating it increasingly difficult.
None of this proves that the United States lags behind the rest of the world in fediverse adoption. I don’t think the available evidence supports a claim that strong.
What it does suggest is that institutions and communities outside the US have sometimes treated decentralized social media as something worth building deliberately.
In Japan, the motivation was partly cultural and community-driven. In Germany and the EU, digital sovereignty played a role. In China, censorship circumvention mattered. In India and Australia, particular communities had reasons to create alternatives that served needs mainstream platforms were not meeting.
The American experience has looked different. Mastodon tends to get attention here when something goes wrong somewhere else. Twitter changes ownership. A moderation policy changes. Another platform does something users hate. People rush toward Mastodon, create accounts, look around, and some of them stay.
That is not the same thing as deciding ahead of time that decentralized communication infrastructure is worth having.
That distinction between reactive migration and deliberate infrastructure-building may be the more interesting question. I just haven’t found the dataset that would let me prove it.
The broader small web is even harder to pin down. I’m thinking here of Gemini, old Gopher servers, personal HTML sites, webrings, and the various little corners of the internet that never quite accepted that five giant websites should become the internet.
I have no solid numbers on where those people live.
My own experience gives me the impression that Germany, the Netherlands, and the Nordic countries are overrepresented in those spaces too. That would make some sense given how often those countries appear in open-source and digital-rights communities more generally.
But that’s a hunch. I can’t point to a study that demonstrates it, and I’d rather call it a hunch than dress it up as data.
If anyone knows of research that actually maps fediverse or small-web adoption by country, with real numbers behind it, I’d like to read it.
Until then, this is an observation built from scattered evidence rather than a documented trend. And when it comes to the small web, that may be about as much certainty as the available data allows.
