Yesterday, Twitter CEO Jack Dorsey made a theoretically huge announcement: he wanted Twitter to stop being a self-contained platform and start delivering content from a decentralized system, changing social media as we know it. He kicked off the plan by announcing a project called Bluesky, which will fund the independent development of that system. But among many people who already work on decentralized networks, the response was a collective roll of the eyes. Twitter wasn’t boldly stepping into new territory; it was stomping into an existing field with a lot of noise and very little detail.
