1b12 vs Guppe groups (community.nodebb.org)

@panos brought up something interesting recently, which is that Lemmy communities don't boost everything (at least when viewed from Mastodon), but just the original post.

I wasn't sure whether this was intentional (because 1b12 definitely specifies that everything is boosted, replies and all). The only explanation I can think of is that 1b12 boosts activities, and Mastodon doesn't understand that, so it's actually an implementation quirk that causes Mastodon to not actually see the entire conversation.

NodeBB used to Announce(Note) and Announce(Create(Note)), and it meant that Mastodon was seeing everything. This was desirable from a synchronization standpoint, but it meant everything was going into Mastodon user feeds, which was @panos' concern.

I think Guppe (which is kind of like 1b12? Not sure) boosts everything, but again, am not 100% sure.

@julian FEP-1b12 only works with activities,
but Lemmy also announces Page objects for (micro)blogs.

@silverpill@mitra.social ah yes, thanks for reminding me of this.

When I refactored my 1b12 implementation, I actually removed the second Announce(Object), but I think I will add it back.
