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?
I was able to get over the majority of the style issues on Lemmy by adding the extension Stylus and installing this theme. https://userstyles.world/style/10440/rediggit-for-lemmy
Hopefully that helps some that want the old.reddit look.
