I switched Lemmy instances in part because lemmy.ml doesn't have the old.lemmy (mlmym) interface available. For a while, mlmym had an official standalone site that could be used to access any Lemmy instance in the mlmym interface, but once they shut that down I was disappointed in going back to the standard Lemmy web UI that doesn't stretch to use your entire screen width. I used some userscripts to make it better but finally ended up moving to lemmy.today because they run mlmym on old.lemmy.today.

It's basically the old Reddit interface and that's how I viewed Reddit for 12+ years, on desktop and on phone. Also, the mlmym/old Lemmy interface actually fits better on portrait phone screens than old Reddit as it hides the sidebar.

I hate Reddit's awful card UI. I don't want giant pictures everywhere. Let me read the headlines and then click to expand if I want. The overly media heavy Times Square looking overstimulation of modern web design is atrocious.
