Very useful, thanks.
As I see it, Bluesky is fundamentally different from Xitter and it is a major step in the right direction. It is short-sighted to reject it because of some technical imperfections.
The fundamental question IMO is whether there is enough mindshare (i.e. users and attention) to allow ATSocial (AKA partial federation) and ActivityPub (AKA total federation) to both be successful. I'm thinking there is. After all, the vast majority of people are still on ad-fuelled corporate social media, with all its internal contradictions.
