#Bluesky is ready to open the network.
Starting today, Bluesky will not require invite codes anymore and anyone can join the network. Later this month, the team will roll out an "experimental early version of federation", allowing other people to run their own 'Personal Data Server' (PDS).
If you want more information on how Bluesky works and what a PDS is, I wrote an explainer of the technical terms here:
