Interesting, I don't see neither lemmy.world nor lemmy.dbzer0.com

It's a bit on the light side. I suggested an integration with fediseer to help people discover instances matching their interests more: https://github.com/fedidb/issues/issues/64

However looking at that issue tracker, I don't think it's being monitored at all.

Kinda bad/traumatizing that this led me to a gore server in the top recommendations for Peertube.
