As a newer user, mastodon.social gets written up in articles more and it's insinuated that it's exclusive, so more people probably join it or did because of that.
As someone who tries to get more people to try Mastodon, that the loli instance is that big puts a lot of people off.
@IronMan yeah, having a flagship instance is both a blessing and a curse.
It's good that people like yourself find out about Mastodon and choose to join a different instance though.
