Do people actually like all of the overdesigned clutter to the point where it makes them not want to switch sites?
To me, the stripped down clarity on Lemmy is a feature. I remember back in the day when people flocked to Facebook from MySpace, in large part because they were sick of eye gouging customized pages and just wanted a simple, consistent interface. The content, not the buttons to click on it are the draw right?
Honestly when signing up they should just be assigned an instance. It does not matter to most users. Then send them the login server per mail
