Once implemented, you can expect proper support in the API, web frontend, and the official mobile clients (that we develop), and we intend to publish the API details in advance so any other client can support them.
We will also be publishing FEPs to ensure that this becomes a standard that can be supported by every ActivityPub implementation.
It will (if all goes fine) support notifications when someone quotes you, as well as controlling who can quote your posts (everyone, nobody, mutuals…)
Here are a sample of the hard questions we need to have answers for:
- Can you quote a post when replying to someone
- Is pasting a link into a post quoting? What if there are multiple posts linked?
- How to handle implementations, instances or clients not supporting quote posts
- How does this interact with moderation? Blocking?
- How do we handle ActivityPub implementations with slightly different formats, like if they support quoting multiple posts in the same status?
