• suddenly a post that was crafted for a local community, with users that have a shared culture and background, becomes exposed to a random audience including trolls and bullies

    That is a good point, that I’ve not seen raised elsewhere. Though to an extent, it is already true when you consider the size of aussie.zone compared to lemmy.world for example. Threads will of course be orders of magnitude worse.

    Besides the human impact of the negative interactions, the technical impact on the server of providing content for umpteen million Threads users is also a non-trivial risk. This alone is making me think defederation is the better option until Meta have a) released details on how they intend to not overload existing instances, and b) as @david@aussie.zone said “Meta can prove they won’t hurt fediverse”.

    Having said that, when Threads announce they’ll be federating I’ll put up some sort of poll to solicit feedback from the wider aussie.zone audience. I don’t want to be making such a major change without soliciting feedback in advance.

    • What does threads federating even mean for Lemmy? They’re a mastodon type platform they can’t see posts, they can’t follow communities can they? I understand mastodon and Lemmy are activity pub in the background and theoretically you can susbscribe each way but how do you actually do that and what does it look like.

      How do I follow my mastodon account from here and vice versa?

      I think this is a moot argument for now as meta aren’t making a reddit/Lemmy type platform.
