No, the story about the Fediverse's growth isn't about MAUs -- not that MAUs can be calculated precisely anyway.
The *real* story -- the one that the tech press should be writing about -- is the growth in:
1. Posts
2. Nodes
3. Apps
This is the beginning of a paradigm shift in social media and how it works.
Look, if I'm a social media app developer, I'm going to look for something that offers me two things:
1. Network effect - something people actively use
2. Protocol and API stability - something that won't change due to someone else's whims
This means the Fediverse.
