@schnedan Thanks!
I heard the name of Damus to days ago. And some news site treats Damus as a replacement of Twitter like this: https://netafull.net/tech/0125149.html (written in Japanese, 04-Feb-2023 posted, 07-Feb-2023 edited)
Not so many but not a few wants Twitter-replacement-service because they like tweeting/tooting/posting (or suitable name in services).
