What is this "sh".reddit.com subdomain that the submitted link has?
The first one is old Reddit, the 2nd is React? / JS FrontEnd based rendering. The 3rd ( "sh" ) if I remember correctly is based on something similar to Livewire / HTMX concept.
I am not even sure if it was accidentally exposed to the public.
But well. The real sin of new.reddit wasn’t really the technical underpinnings, but the UI design. Here it seems even worse in parts: permanently clicking just to read the comments.
I don't know who designed this, but it is truly awful.
