Mastodon's specification for Quote Posts is finally out and... It's not bad!
It is based on FEP-e232, on top of which they add a quote control mechanism. I believe that quote controls in decentralized network don't make much sense, and currently I have no plans to implement them, but from a technical perspective, the design is quite good. Hopefully it stays that way
