Over the course of the last month, members of the Berkman Klein community, representing academics, activists, lawyers and technologists, came together to discuss the Twitter BlueSky project. The discussions culminated in this “meta-proposal” for the BlueSky team and community, which presents suggestions on how to go about considering proposals and building out BlueSky.
Twitter (at least their CEO) claimed they were interested in a decentralized form to allow more communities. ActivityPub, Matrix, Status etc were mentioned. But it seems these harvard people would like to build a new one instead of joining and improving the existing.
