Bluesky was funded as an independent entity when I was CEO. Twitter can’t direct them. Goal was to build a protocol for social media. Nostr is that and more, and taking a different development model and path. TBD’s web5 provides some similar infrastructure, speficially to decentralize/make permission-less DNS and Certificate Authorities. I imagine there will be cross over and sharing/stealing of ideas between all 3. And everyone is better for that.
Except Mastadon. I feel the 3 above means the slow death of current fediverse. But, if they stick around, great! More experiments the better. One of them will get it right.
