Instead of posting on a personal #IndieWeb site (& POSSE copies), some post primarily to a #fediverse instance and syndicate to Twitter, or vice-versa. How to reply^1 to such posts, e.g.:
Reply to a toot (& POSSE tweet): https://tantek.com/2023/019/t4
* @-@ (Twitter @-name)
This is a variant of case (2) in https://tantek.com/2023/018/t1/elevate-indieweb-above-silo.
We can update the directive and two questions & answers in that prior post accordingly:
* Elevate #IndieWeb domains above @-@ addresses, and those above any silo identities
1. Do they have an #IndieWeb domain? Then @-domain mention them^2, like you are speaking to them at their domain identity. This will notify them there, or at least reinforce their domain’s importance.
2. Was their post only published on a #fediverse instance (and/or silo), or was it POSSEd to a fediverse instance (and/or silo) and do you plan to federate (and/or POSSE) your reply^3?
Then use their @-@ address or silo @-name, or @-@ (silo @-name) for both, or (@-@, silo @-name) parenthetically following their @-domain if (1). This will notify them on that instance (or silo), and may help thread your POSSE reply.
When posting a reply, you (or your CMS automatically) should explicitly link with u-in-reply-to markup^4 to the post your are replying to, and any of its syndicated copy permalinks on destinations you plan to POSSE your reply (see also multi-reply^5).
