This looks interesting, but if you don't have creepy and opaque admin controls and algorthimic manipulation that create a thousand little tinpot Larry Ellisons, you should highlight that.
Could you please explain exactly why you think no one you know uses Mastodon? I'm trying to figure it out. I, personally am hesitant to use it first and foremost because Mastodon (and many of its lesser known alternatives) is a variant of micro-blogging (I'm appalled how extending character limit beyond 500 apparently counts as a feature in Fediverse!)
The instance owner has absolute anonymity and absolute power to snoop with no access logs and no known identity. CCPA? GDPR? Access controls? Good luck! You can leave the instance, but you're leaving all your data behind for them or any future owner of the instance to do whatever they want with... forever.
And even if you trust them and everyone they will ever meet, people can and do store their server logs unencrypted.
Then argue they can't help it and you don't "get it" because that's just how the architecture has to work in order to... well it's not clear why this is a good design for the user or any better than other social media.
1) You still don't own your data
2) You still don't have any privacy
3) Every single part of the user experience is inferior or confusing and the people making it don't care because they're focused on doing what they can to connect kids with anonymous instance owners.
Because that's why no one I know uses Mastadon.
