Word is Lemmy and kbin are working to make the process more automated, so if you click a link to a community/magazine your instance want aware of it’ll start aggregation without having to manually do the search. Downside of going with a free, open source, decentralized solution is there aren’t a bunch of devs dedicated to updating the platforms for a living, so features will roll out slower.
Kbin is supposed to be able to communicate with mastodon and most other softwares on the fediverse, which is why it exists. Definitely needs some tweaking, though, there’s like one dev right now.
