The issue with mastodon communities is that they don’t use the same type of fediverse tools. You could maybe follow people from mastodon, but the apps or Lemmy/kbin will need to implement a compatibility with those fediverse websites.
To follow communities outside your instance it’s a bit less optimised currently as the instances don’t scrape all the communities from other servers.
So to find them, either someone else had to search it and subscribe to the community for the server to show it when you search for them, or you’ll have to show the server where the community is :
For example a community from your instance : !apolloapp
You can notice that I put a ! Then [community] and @[server address].
You will often see this presentation under the community name when clicking on a community : !apolloapp This is what that means.
If you were on another instance, to find the apolloapp community from reddthat.com, you’ll need to search for either : !apolloapp Or reddthat.com/c/apolloapp
I don’t know if apps are able to search like this, so you may need to go on your account in a browser and search from there.
Also as stated in another comment, there are websites to search for communities, like Lemmyverse.
However you can find communities to replace the reddit ones here :
A few days ago when I was using /sub I only saw the magazines that I subscribed to. This seems like the intended behavior. But now I see threads from all kinds of magazines plus the ones subscribed under /sub. How can I hide the magazines I am not subscribed to from the subscribed threads view?...
are some communities on this Lemmy thing inaccesible by searching? If so, how to find them?
I can not believe that there is, for example, no furry communities here - yet there are none in search results…...
Kbin doesn't respect my subscription feed anymore or I don't understand it. (kbin.social)
