So as per @Kierunkowy74's reply to me, limiting (basically what I described) is a feature on Mastodon already. It basically just sets things to follower-only mode on a per-instance basis. I'm not sure how well that would translate to the threadiverse, but I do think some level of opt-in integration would be best.
To go on a slight tangent: I've never used Imgur as anything other than a image hosting site, but I'm aware it has people that use it as a social network in its own right. Whenever I've hosted anything on Imgur in the past - even images that don't need any context - I've noticed it always ended up downvoted and sometimes with some negative comments, while the reception on reddit was generally far better. It doesn't bother me - like I said, I just used it as an image host - but it's clear Imgur has its own culture. Threads could be the same, and trying to merge its culture with ours could prove difficult.
I don't know what full-on federation with Threads would look like, but federating vote counts could definitely lead to Threads culture overwhelming threadiverse culture. But I assume that's also something that can be done on a per-instance basis; I know kbin (which I use) already doesn't federate downvotes from other instances, for example.
I'm not sure I have a fully-formed opinion on it all yet, unfortunately. I don't like the idea of cutting Threads off completely unless they do something to earn defederation. I think finding a way to smoothly federate with Threads could give the fediverse a boost in users that could be significant for more niche communities that haven't managed to find a large enough audience yet (because yes, I'm still missing some of the smaller communities from reddit). But I do also think there are very valid concerns about both the long-term and immediate impacts Threads could have on the fediverse.
True. But, personally, I think it has all the downsides of pre-ordering but at extra cost. The game could be an absolute disaster (Suicide Squad, anyone?) and there's no way for anyone to know that. Not waiting to be able to properly inform yourself about what you're spending money on is so stupid.
I'm honestly reaching the point where I think pre-ordering games should be legislated against. Sure, it's only stupid people being parted from their money, but it's clear some consumers need protecting from themselves and it's only really the corporations that would lose out.
