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the latest MAU figures at Fediverse Observer, with adjustments made to the totals for Piefed (due to undercounting by outdated instances, as noted here; I used @Vicinus@piefed.zip’s suggested estimate of 7,200 Piefed users) and Mbin (due to tardigram.com having a duplicate listing).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.
While thats true, if my friend whose biggest interests are science informed dog training and animal genetics joins the threadiverse there are not enough people here who genuinely really care about those subjects to actually sustain any of the social connection she’s looking for around them.
If my friend who’s super into basketball and competitive league of legends join she’d have at least a couple people to talk to, but its fundamentally not what she’s looking for to talk to exactly 3 other people who care about the thing she’s into.
I try to remember that as much as I love the fediverse and feel at home here, it has real limitations for lots of people, and its okay if its not in a state they can go enjoy very easily. This is a space that I am passionate about and want to contribute to. I don’t expect everyone to do labor to invest in a space that isnt their passion just to chat with folks when they have the ability to chat with folks somewhere else, even if that place has bigger picture downsides or harms associated with it.
