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?
You can interact with other instances from your home instance. However, it's easier imo to just sign up a couple of accounts across a few that you like and switch between them as you feel like it. Pretty much all the apps for you phone support multiple accounts too.
The key is to not become overly attached to one account like Reddit. Remember that any of these servers could go down permanently at any time and the important factor is the meatbag behind the account, not the account itself.
