While this is a great writeup on Lemmy instances, the thread was specifically about Mastodon and it’s numerous forks. I believe they use the same tech but are vastly different things. The instance I found wasn’t quite Mastodon apparently, even though it works very similar and the app designed to connect to a Mastodon instance wouldn’t connect to it.
It does get all manner of interconnected doesn’t it?:-)
Your account is on Lemmy.World, this community is on Lemmy.World, and pawb.social is a Lemmy instance, so I thought we were talking Lemmy.
I don’t know much about Mastodon specifically, although I do know that Mbin servers - primarily fedia.io - can connect to both Lemmy and Mastodon instances.
Changing the software in the drop-down to Mbin shows similar stats for instances running that: https://mbin.fediverse.observer/list shows those, and sorting by Active Users reveals that fedia.io contains ~82% of all users on instances running Mbin.
In contrast, virtually nobody is still running Kbin: https://kbin.fediverse.observer/list - just one instance with 48 active users.
Btw the newer Lemmy alternative “PieFed” is growing: https://piefed.fediverse.observer/list, though fewer than 200 users total world-wide, so more something that we keep eagerly anticipating than something currently and fully “here”:-).
Anyway, perhaps the app just needs some time to be able to connect to that new instance? Rather than wait though, you may want to contact the developers - they could potentially add it right away and rather than resent the contact even appreciate your feedback and interest, maybe? :-)
