From kbin- how do you see a list of communities on lemmy.world? I've been navigating to https://lemmy.world/communities in a separate browser window to discover communities to individually search/subscribe to from kbin.
Go to https://kbin.social/magazines and turn on local and federated, then hit the search button. For some reason all the top "hot" are kbin but the "new" and "active" are various.
Then if you specifically want, say, lemmy.world, type that into the search field and hit search again. It will all show.
Yea, a lemmy instance will show the same kinds of results for federated communities but there is no substitute for viewing the local communities from that instance.
The article specifically says you can't search federated communities from kbin, but you can from Lemmy. This is just incorrect, both allow you to search local or local and federated.
Click on the tab Magazines at the top, select local and federate, put lemmy.world in the search box to see all lemmy.world communities. If you want to check for community with certain keywords you can try putting [keyword]@lemmy.world. It can search for the keyword in both the name and description, but not extensive as if you'd search on lemmy.world.
This can use some improvement, but it's not a Kbin problem though, since Lemmy is even worse when it comes to searching for communities outside each instance.
Ah, I see what you mean now. In that case I don't think you can do it on Kbin natively rn. There is this website though, which might help a bit. At least imo it's easier to use. https://lemmyverse.net/communities
You can just filter for only lemmy.world. When you find a community you want to join you'll have to type the handle of the community in the search icon to the right rather than in the Magazine tab for communities that doesn't already have a copy on your instance.
