I'm not new to Lemmy, but I've only recently gotten Voyager (+ a brand new acct) and it's pretty confusing. I'm looking for an option in the app that shows all possible communities for a given instance. Is that possible?
Also like others have said, you could try using the search function in the Voyager app but you kind of have to know the name of them first.
I'd also try different sorting algorithms in All every now and then, like new, hot, and Scaling (which weighs smaller communities higher, a good way to find new places).
Glad to help! Just a note that the *last community I mentioned is for people to encourage each other, gather support, and get ideas on how to grow communities that might be small or nonexistent on Lemmy, since we're still quite new.
So if you want to discuss something that you think others would be interested in that you haven't spotted on Lemmy yet, feel free or start it and grow it!
Quick take, I imagine posting more content to nascent communities so they make a bigger presence in the main feed would likely be a big help. Unfortunately it seems a lot of great people are still at the other place, probably because of the active, niche communities there, not to mention some of them thinking Lemmy is more complex or difficult than it really is...
