I don’t know what discord is, but I find that every social media owner/admin and developer can be reached at discord. Another thing is Matrix.
I’ve got no clue about these two platforms but I believe that they’re not a part of the fediverse.
I very much wish that replicas of these were available on fediverse, so that we could interact with them from our Mastodon, lemmy or other Fediverse handles.


IDK if that’s a good idea, even Mastodon and Lemmy don’t really interact that well. It’s easier to just make a separate account for each type of platform.
I’ve interacted on lemmy from my mastodon account, but l spend more time on Piefed now.

Lemmy vs Piefed doesn’t really make a difference, because it’s the same type of Reddit-style platform (also called “threadiverse”), while Mastodon is Twitter-style. The interoperability isn’t great IMO, because the usage patterns are quite different. e.g. if you reply to a Mastodon post on a threadiverse platform, the OOP on Mastodon won’t see any of the replies, and are probably not even aware that there are threadiverse threads about their post. IIRC you need to @ the OOP in each of your replies, which you need to do manually in the threadiverse, which isn’t particularly obvious if you never use Mastodon yourself.
