Yes to recreate threading someone would have to scrape the whole data of a thread and all sorts of other issues. But authored threads with that succession of OC posts might be re-constructible. I have various threads in that progressive structure vein on Twitter that I am planning to bring across from Twitter to Calckey for example, but with microblog there is no community selection needed, which would be an extra hurdle.
Oh if you want a quick primer read on Fediverse adventures I turned my last 8 months knocking around here in to a short (Matrix themed) thread. The communities here are really friendly & helpful, there’s lots of people who answer questions etc. Have fun! :) https://calckey.social/notes/9er7rlxy6r
A quick overview of some of the larger platforms in the #Fediverse
If the Fediverse is planet earth. Lemmy is 1 country, each server instance is like a village town or city. Other countries where you can talk to follow users etc are Mastodon, Pixelfed, Misskey/Calckey, Peertube, Friendica, etc Like following Twitter users replying etc from inside Reddit.
LOL! sorry ;)
