Lemmy is part of the Fediverse, a network of independently hosted social media platforms that can communicate with each other.

Lemmy is a software which runs on many websites see for a overview:

https://lemmyverse.net/communities

They are connected and show each others content.

There is other software which can do it too like PieFed and mbin.

You could try https://mastodon.social/explore

Just keep in mind, lemmy.world is one of many lemmy sites and most of them are interconnected to have the capacity to interact and explore other users content.

Edit: Or you could try ordinary forums. https://en.wikipedia.org/wiki/List_of_Internet_forums

Although it’s not in the fediverse I quite like reading https://tildes.net. It’s quite slow paced but the quality of conversation is quite high in my opinion.
