Those Mastodon stats in full. Still doubtful that Gab is the largest instance. Wait 3 months and then count active users....

The most 'popular' site Pawoo is running Mastodon 2.4.0 whereas the latest is 2.9.2. That would worry me.
@andyc I've seen quite a few on 2.4.0. Maybe the idea of a version change is a bit scary for the bigger instances.
