@julian said in Cross-posting is coming to NodeBB!:

different communities with (sometimes very) different values would suddenly co-exist in the same space, leading to some very negative interactions.

This is something I'm very concerned about, and it's one of the primary reasons I generally oppose efforts on Lemmy and Piefed to enable virtual community mergers and whatnot. I'm getting old and all that jazz, but from my perspective, the Internet was a more vibrant, more productive, and more fun space when communities were small enough to see other members as people, and where usernames and avatars were immediately recognizeable, rather than the giant morass of faceless voices shouting about in dark, giant, overfilled rooms. Just from a cultural homogenization point of view, it's been a negative.

But shared comments on individual posts like this poses an even bigger risk, since, as you point out, a single share to an unscrupulous server means everything is on fire.

Post syndication is one thing, but comment syndication seems like something that needs a lot of transparency, release valves, and a high degree of opt-in and opt-out control.

Like, there are definitely Lemmy and PieFed communities I'd happily sync comments with, but there are a bazillion others I would not. That means, as a moderator, I'd need black-lists and white-lists for remote communities at both the category and topic level, while as a poster I'd want some level of control over where my topics or comments can go, and maybe even the ability to flag topics or comments as local-only (which is something that maybe should be considered just from a basic federation standpoint; I've seen this in action on Misskey-based microblogging sites, and it has value).

But still, despite those hefty reservations, I cannot deny that I'm really very excited by this.
