From the article:
"Beehaw is relatively new and relatively small at the moment, but it’s one of the closest approximations of what Reddit is that you’re going to find, and well worth investigating as a Reddit replacement. The interface even looks a lot like Reddit, albeit without a lot of the on-screen features and furniture that build up over almost two decades of operation.
Have a read of the Beehaw mission statement and you’ll see the platform is committed to avoiding the “hate speech” and “disinformation” that’s prevalent elsewhere. The communities available right now cover everything from neurodivergence and people of color to literature and gardening, so you’re sure to find something of interest here."
Defederation isn’t preferable but it’s a great feature of the fediverse to keep communities safe. It should only be used as a last resort when all other modding tools have failed. However, Lemmy is so new that those powerful moderation tools don’t exist yet. That’s the only reason those instances were defederated, they’ll be federated again when the mod team can better control the influx of users as better tools are developed.
That being said I’ve hardly noticed a change in engagement on beehaw tbh. My posts and comments get just as many replies and upvotes as before defederation.
