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?
Just wait till they have to use the reddit app only. Plus if these people want to they can invest there time and run a Lemmy instance. Develop their own tools to make it look the way the want. Rather than complaining about free too hosted freely by people who care.
