@kevinmarks that's only true for mastodon URLs -- remote servers could have `@a@trwnh.com` map to `https://ap.trwnh.com/317390182739802718903` via webfinger, which contains neither the original username nor the original domain name. the `@user@domain` is the easiest way for people to share with people without worrying about what URL it will resolve to on the backend (or, in mastodon's case, *not* resolve to -- mastodon uses webfinger as canonical address, unfortunately, since it predates activitypub)
@trwnh No, urls are the easiest to share, as you can click on them. And they resolve to have links in, which code can look for as well as people.
trwnh.com doesn't have an lrrd link in it's host meta and webfinger 404s
https://trwnh.com/ gives me useful links, and with one more rel=me added would give you a green tick, like you did with https://abdullahtarawneh.com/ (which has no webfinger either, but has a nice h-card) https://indiewebify.me/validate-h-card/?url=https%3A%2F%2Fabdullahtarawneh.com%2F
