Interesting, I hadn’t heard of that. Does everyone who’s following the old account automatically refollow you when you do that?
IMO it’d still be useful to be able to use an identity you control, like a domain name. I’ll have to find those proposals you mentioned.
That’s only for showing a domain on your profile. What I meant is using a domain as your username, so if you own
example.com
and used that as your username people would mention you by writing@example.com
. A DNS record delegates the domain to the right server.
