Yeah, good that you guys are making such lists. It took me a few days to truly understand the "threadiverse" but now, as in right now, I am stumped trying to understand how does everyone integrate with Mastodon (which I understand to be not-Twitter) and then what do all of the other platforms even do! What is Misskey and how is it different from Calckey or Akkoma or Friendica.... And how do they interact between each other. I am very confused but also very excited.
