Reddit seem to have switched to the newer, even shittier UI by default.
You're viewing a single thread.
I was very confused for a moment as this is how my Lemmy looks - I'm using the Photon interface (e.g. https://photon.lemmy.world/) Pretty much identical.
Thankfully, unlike reddit, you can always change this appearance with options or with another Lemmy app.
not a fan of the layout, but photon is still way lighter than reddit
Ya I noticed that shreddit uses a similar layout to photon
