Lemmy active users grew by an astounding 1600% in June
From 2,997 active users across all lemmy instances at the beginning of June, the number increased to 52,797 by June 30th. Source.
An active user on Lemmy is "someone who has posted or commented on our instance or community within the last given time frame.” Source. That means lurkers are not counted as active users. There are currently almost 200k total users spread across the top 10 non-bot lemmy instances.
I'm optimistic and also hope this is different than the whole "Voat" exodus (which in retrospect was really dumb, and fuck Voat). It's a much different situation. The technology and vibe here is good for now, and I hope it gets better.
