Good hints, but these events likely were not very relevant.
While Lemmy gained almost 200,000 new users in the last two days, the active users increased by less than 3,000, just about the same as pretty much every two-day period recently. So pretty much all of those new users are inactive. That's not hordes of Redditors coming over and exploring Lemmy, that's hordes of bot and sleeper accounts being created.

I think most are still figuring out how this all works. I barely did anything the first couple days too. Its a bit confusing at first and takes some time for people to find their place.

I'm pretty sure that's just how social media works. Only 1-3% are active users, while the rest of it are lurkers.

Well, for Lemmy 1 of 5 users was active right before the jump, and when the 219'519 new users (*) came, the active user count only increased by 2,873, so 1 of 74 new users was active.
When hundreds of thousands of users are so interested in a new platform that they storm it in a few hours, wouldn't you expect them to initially engage a lot, rather than basically all being inactive from the start? Especially if they are early adopters, coming just days after most of the other users which turn out to be pretty active?

(*: Apparently the latest numbers from fediverse.observer are live or updated multiple times a day, so it's again some 20,000 new users since my earlier post which already had different numbers than the OP.)
