@vkc I tried lemmy and failed to understand the activitypub bit of it. Also: how do I find interesting ‘subreddits’ in the Fediverse? I need to educate myself. Forums and Reddit itself seemed somewhat easier to discover.
To discover Lemmy and Kbin communities, try LemmyVerse. They scan multiple instances daily to ensure the full catalog of things to subscribe to. As soon as you find a community of interest, you can copy its URL and paste in the search bar of your instance, it will perform a lookup.
