I'm one of the people who has very recently tried Lemmy and decided to drop Reddit. Initially because I will no longer be able to use SyncForReddit, but now also because I just like the vibe a lot more here than Reddit.

I'm not a massively technical person, but I understood the broad concept of federation - different instances/servers that sync to form a big conversation/forum of sorts.

I heard a lot of people joining and saying positive things about lemmy.world, so I signed up there.....and that's it.

But, am I using it right? Is the idea to sign up in one place and use it to participate across the LemmyVerse/FediVerse? Or should I be seeking out lots of niche instances of interest?

I hear lemmy.world is the biggest instance. What if most people end up here, does that defeat the purpose? Is this inevitable?

You need a critical mass of users, so a quiet instance with few posts is not attractive. If I search for Xbox, there are lots of empty places or places with 3 posts. If there's one big one (often ends up being in lemmy.world) that's where I'm subscribing.

How are you using Lemmy, are you participating in a bunch of instances or just one?
