Yes, it really does!
Since my post yesterday, lemmy.world has added about new 2600 users, bringing the user count to 28361 users. It's the clear second-largest lemmy instance out there and quickly closing in on lemmy.ml's 36k users (not taking new signups).
Interestingly, third-largest lemmy instance beehaw.org seems to have lost about 275 users since yesterday. Guessing some people were pissed off about its defederation enough to delete their beehaw accounts?
Excellent news! It's so lovely to see lemmy.world and the threadiverse as a whole grow. It's only gonna get bigger from July 1st
