Beehaw.org defederated themselves from Lemmy.world and sh.itjust.works. How does that impact their communities? Not much, as it turns out -- as long as you're not a user on those instances.
Last week, Beehaw.org announced that they are de-federating themselves from Lemmy.world and sh.itjust.works. All three of those Lemmy instances are big, with dozens of very active, popular communities. So how does that impact you as a Lemmy user?
When Beehaw.org says they are "de-federating" with Lemmy.world and sh.itjust.works, what they mean is that they've blocked Lemmy.world and sh.itjust.works from participating in communities on beehaw.org. That means that users who registered accounts at lemmy.world and sh.itjust.works won't be able to participate on any communities at beehaw.
If you're a user who registered at a different Lemmy instance, such as our own Lemmy.ninja, you won't be affected. You will still be able to participate in communities from all three of those instances.
There's another impact, however. Sh.itjust.works and (especially) Lemmy.world are sites with a large number of users. By defederating, Beehaw has eliminated a large number of users from participating in their communities. That means that the communities at Beehaw will become less active, and competing communities on other instances may start to grow.
