I found it complicated at first (didn’t know which instance “will last”, where to register to not lose anything when instance admin decide to turn it down), but now it’s going good. We are missing mobile apps though.
What’s are your thoughts about Lemmy/kbin?
This would be especially great if apps like Jerboa allowed automating the grouping process (opt in by user maybe). Some sort of maintained lists of equivalent communities across instances, so the app can easily allow you to subscribe to one community or, in a more Reddity way, a federated set of communities with one tap.
