I Iike both slrpnk and blahaj but it's not like their domain names are magically not also part of this alphabet soup they're talking about.
It's... kinda the point of federation and decentralization.
Sure, Reddit or Facebook have brand recognition, they're also centralized corpo garbage.
If a blahaj user wants to share a SJW post, but finds the sjw domain untasteful, they can also just share their instance's URL for said post.
I think most (especially mobile) clients simply don't have this option and will always copy/share the "fedi link" - the url where the content is canonically hosted. all other URLs are simply cached representations of the original content.
Honestly, that's one of the things I like most about lemmy.
The web UI just works fine in a mobile browser. I was so used to garbage sites going out of their way to gimp the mobile experience (to push you into their app) that I had forgotten how pleasant it was to just use a browser for this.
Multiple tabs, ublock origin, bookmarks, etc.
I appreciate that there are apps available, but it's nice not needing an app.
I may be remembering it wrong, but I think world was one of the few accepting people without a referral during the reddit migration. That's why I use .world. I also don't really understand federation besides it means I can see other instances, but I only barely know what that means. There were a lot of "what is the fediverse" posts when I first joined, and they were helpful, but maybe too simplified?
I also remember thinking .world and .ml were the defaults when I started.
This comment would be more relevant a year down the line if perspectives shifted and users begged for sanitization, but:
Is it technically challenging or financially costly or otherwise problematic to mirror content to another subdomain, or domain mask or something? I thought of this after seeing oldsh.itjust.works:
I'm not an expert on the specific of this, but changing the domain for the UI (as in oldsh.itjust.works) seems a lot easier than changing the domain for the backend, which includes federation with all other instances.
I don't know of any way to change the federated stuff without breaking pretty much everything and starting over.
Maybe there is and I just don't know about it, or maybe there could be an easier way at some point.
