I am Stine. Comfort the afflicted. Afflict the comfortable. High School Wrestler™. Can usually correctly use the past tense in French. Suffers from clinical depression. @stinerman@mastodon.social on Mastodon.
I’m not sure it’s as big of a deal with Lemmy. Threads data doesn’t map very well into Lemmy and vice versa. Like with Mastodon, I can read this post and comment on it, but it’s not really a great way to interact. I think it’s a bigger deal on the Mastodon/Calckey/etc side. If IG/FB federate then it becomes a different story, IMO.
No, not in the example that you’ve set up. The username is always @user@domain. This is like asking if you can have the same email address on Gmail and Hotmail or whatever. You can have the same user part, but not the domain.
People that have used user@x.domain and also user@y.domain is allowed because they’re different domain names.
Here in the US there’s also a long waiting list for surgeries and specialists. It’s called “I don’t have enough money to pay for it” and people wait until they have the money. It’s too bad that people in both countries have to wait longer than necessary for medical care.
