Decentralisation sounds good. I read the FAQ on your page, and it might be worth labouring some of the points it made a bit more here. I didn't pick up on those concepts on first reading this post.

Eg, people here are are worrying about doxxing, even though it looks like the big selling point is that you don't have to sign up to your site to use it.

(Counterintuitive, when the first thing your site shows is a sign up form.)

You might need to be quite patient and willing to repeat yourself a lot before seeing any movement. Especially if people are going to do things like see the letters "fed" and go "Hey you're the Feds". I mean, in that exact case you might just decide you don't want clientele like that anyway, but there is a middle ground.

I definitely like the idea of a more long term solution than just copying Reddit with the devil you know in charge this time.

I haven't read or thought about how privacy, censorship, moderation, etc play out under the new system.
