"Bluesky: Jack Dorsey's Social Network Now Open to All"

Bluesky, a social network championed by Jack Dorsey, has opened up for anyone to sign up, moving away from its previous invite-only model. The platform, resembling Twitter in many ways, offers more customization options but does not yet support direct messaging. Bluesky plans to allow users to move their data to competing social networks and aims to be the last social account users will ever need to create. However, achieving interoperability with other platforms may not be straightforward, as Bluesky uses a different federation algorithm called the Authenticated Transfer Protocol compared to other services like Mastodon and Meta's Threads, which use ActivityPub.
