For Example:

@eapl.me@eapl.me A way to have a more bluesky’ish handles in twtxt could be to take inspiration from Bridgy Fed and say: If NICK = DOMAIN then only show @DOMAIN
So instead of @eapl.me@eapl.me it will just be @eapl.me

And it event seem that it will not break webfinger lookup: https://webfinger.net/lookup/?resource=%40darch.dk (at least not for how I’ve implemented webfinger on my sever for a single user;)

I don’t get why displaying nick@domain is preferred over just @nick in the first place. The twtxt world here is so small (and hopefully will always be) that duplicate nicks are just not an issue from my point of view. And even if there are several feeds with the same nicks, one probably does not follow both of them. Yes, there’s the birthday paradox, but I’d guess we have a slightly larger nickname space than days in a year.

my 2 cents here…
I agree on displaying a short @nick.

We could hover on the nick to see the full detail which could be @nick@domain.tls or the full URL
Also it could be a display option in Preferences in case your account starts showing many collisions.

The disambiguation for collisions is the .txt URL and the nick inside it, right ?

and going back to a handle you could input in your client to look for the user/file, like @nick@domain.tls I think Webfinger is the way to go. It has enough information to know where to find that nick’s URL.

@prologic@twtxt.net does that webfinger fork made by darch work OK with yarn as it is now? (I’ve never used it, so I’m researching about it)

Are we talking about profile view heading, heading of posts or inline mentions?
In yarnd I recall there is a setting for changing the heading of posts, but not for the two others as of yet.
I like the hover option for inline mentions. For the other places some like how yarnd does it in two line or “ nick (domain.tld) ” could also work.
