@thenexusofprivacy regarding relays, again, a set of independent silos is not a decentralized network. What matters to me in decentralization is the diffusion of power. I don't know if Blacksky can provide that, but I know that today Bluesky cannot.
I am running my own blog on my own server. Doesn't make Google Search, which indexed it, any less centralized though.
All that said, I'll definitely dive into Blacksky more, for sure. It does look super-interesting.
