Hi, there,
We are using Buffer, and nothing is being posted automatically.
Buffer posts directly to Mastodon, just as it does to other channels. @amapanda_ᚐᚋᚐᚅᚇᚐ uses it for that purpose, I believe. And, to my knowledge, no second class citizenry is being created.
I am not familiar with the ticket you reference, nor have I ever seen it on a CWG meeting agenda.
As to the added detail re: the Mastodon links, yes to all! Thanks for expanding the details.
