In the graph above I’ve arranged the 28 Threadiverse instances with at least 200 monthly active users (MAU)—orange instances running Lemmy, green Piefed, and red Mbin—on the basis of which instances they defederate.

Each instance has its MAU count listed below it, sourced from the latest MAU figures at Fediverse Observer, with adjustments made to the totals for Piefed (due to undercounting by outdated instances, as noted here; I used @Vicinus@piefed.zip’s suggested estimate of 7,200 Piefed users) and Mbin (due to tardigram.com having a duplicate listing).

After adjustments, there are an estimated 43,287 monthly active Threadiverse users (35,184+7,200+903), of whom 87.84% are on the 28 largest instances. The percentages listed alongside the MAU figures correspond to each instance’s share of the total MAU count.

Defederation data was sourced from Federation Checker. The tool doesn’t support Mbin instances, so I left fedia.io in its own category. If any defederations are missing, feel free to let me know. Ideally such a chart should also include community blocks to better illustrate which instances block what, but that data doesn’t appear to be as easily searchable.

I also noticed cases of some instances being listed as being defederated by another instance, despite not appearing on the defederation list for that instance (i.e. reddthat.com and lemmygrad.ml are listed as being mutually blocked, despite neither having the other on their block lists). In testing that federation, I noticed that !wholesome@reddthat.com did not federate to Lemmygrad while !memes@reddthat.com did, so clarification on that matter would be helpful.

While I’ll update my generalized chart as needed to correct errors, perhaps at some point an automated federation mapping tool similar to the one feddit.de formerly hosted could be developed to more completely illustrate instance federation.

      The MAU numbers for instances were sourced from Fediverse Observer and calculated as a percentage of 43,287 for the percentages, but here’s a table of the defederation data:

        What the hell are Hexbear and Lemmygrad and what did they do that everyone’s blocking them?

          Lammygrad are Marxist Leninist, Hexbear are dirtbag leftists. That makes them the natural enemies of center-left and centrist instances like .world.

          In my opinion it comes down to a disagreement over capitalism. One side wants to destroy it, the other side wants to moderate it.

    I say, I really don’t get why so many people stay over on Reddit.

    This might be a micro version of the actual future internet, where we walk away from the global model and split it into ideological countries who believe the best way forward is to stop talking to the other group.

    We’ve come a long way from drawing artificial lines on maps.

      The fediverse is great if you fall into the like 5 interests that are pretty well represented here.

      But if the communities you wanna engage with aren’t really active enough for potential posters to not just forget they exist, or you don’t really want to be on a platform where 75% of the front page is news or memes about the state of the world politically, its not neccisarily a great replacement to reddit

      For me it happens to cover enough of my bases, but I can get why it wouldn’t for many people.

        I’ve said this a number of times over the past couple days, but if there’s an instance for mirroring subreddits, where niche subreddits that don’t have an equivalent here yet basically get a carbon copy and a repost bot to stock them with relevant stuff from over there, that could fill in some of those gaps and make the fediverse a more attractive alternative.

        It won’t have the same level of engagement right away, but it will provide a place for that engagement to occur, and as more people start using it it will create a network effect. As things stand now, we’re missing a lot of those niche communities.

          This approach is honestly a non-starter. It lacks organic engagement, and most of the posts from people who do this have no comments or very few. It also tends to end up with one person flooding with a bunch of shit they didn’t read. Personally, I usually block this as meaningless attention seeking, and I’m sure I’m not alone.
