OK, let me try something.

Hello
@Gargron! It’s the first time I’m addressing you, so let me first of all say a big THANK YOU for your contribution to the #Fediverse! The reason I’m writing this is that I saw that @mastodon recently announced quote posts - I think that’s a great decision! As you probably know, #Misskey and #Calckey already have an implementation for quotes, where the quote appears under the original post (like a comment, but flagged as a quote), and where the original poster is notified when quoted.

I don’t know how you intend to implement this feature in Mastodon, but since our users interact with each other, I thought it would be a good idea to suggest some direct communication with
@syuilo (who originally implemented this in #Misskey) and @kainoa (our lead dev at #calkey), to make sure our implementations will be compatible. Even if there are concerns and things that you’d prefer to be done differently, I think that they should be discussed, and #Misskey and #Calckey should consider adjusting their implementations, so that they interoperate seamlessly with yours. The idea is, let’s see if it’s possible to find a common way to do this, so that users have a smoother, safer and more consistent experience, on such a sensitive issue!

I think that the widest possible interoperability in the
#Fediverse is to everyone’s benefit, and it gives a better experience for every #fedizen, no matter what platform they’re on. Let’s try to work closer together on common features or problems and find common solutions - we’ve got this.

Posting this publicly because I think that more cooperation between fedi platforms is something many people in here would love to see – myself included! Hoping this is received positively and in good faith. United fedi is best fedi =)
@panos @kainoa @syuilo @Gargron very cool thought. I was wondering, in those platforms, can you opt out of allowing quotes of your posts, either as an account setting and/or at the post level? Doing that, including the ability to do so retroactively, is another of the interesting ideas I've seen floated to mitigate some of the concerns around quoting. Just curious, I've been meaning to look into the *key apps but haven't had the time, so I should just know this but don't
@mrcompletely @[email protected] @syuilo @Gargron No, currently quotes are not opt-out. My personal opinion on this is that this should probably be addressed by visibility settings. If you make a public post, well... the same way someone could link to it, they can also embed it in their post (which is what a quote essentially is). We don't allow quoting non-public (followers only) posts, obviously.
However, if that's something Mastodon wants to do, perhaps we could talk about it and find a better way that would address all concerns. This is the idea behind the post, we already have this feature, Mastodon intends to implement it soon, so perhaps see if there's common ground and work on a more unified approach, that could offer more consistent experience for users among
#fedi platforms. After all, our users all interact with each other, so it would be nice if a #quote worked similarly in #Mastodon, #Misskey, #Calckey, #Akkoma etc. I think it could help with addressing concerns and confusion about how others do it, who can do what etc.
@panos @kainoa @syuilo @Gargron Makes sense. I do think there's a case to be made that "public but not quotable" is a valid distinction but it's not my case to make as I am not on the design team or actively engaged (as a professional software design/dev lead I have Thoughts but it's not my project and I am not under the impression everything needs my input). I do think your desire to coordinate the major points of feature design across federated platforms is a valid and well considered one.
