Lämp.

A lot less than 20% when it comes to specific subjects. The great thing about reddit was finding communities around just about every topic or hobby. If 100 people had a passion for something they could meet on Reddit and still have a comfy, somewhat active sub reddit.

On Lemmy you’ve got generic technology, generic news, generic videogames, generic pics, and almost everything else doesn’t get enough traction to keep living. It’s a basic population problem, the fraction of people knowing about Lemmy is just not enough to gather around shared stuff. Even those that do use Lemmy are probably not aware of every community attempt that could interest them.

I still see more communities being abandoned than new ones appearing.
