@J12t @mmasnick Mastodon is truly open and federated but I think Bluesky is nevertheless contributing some important ideas to advance the social web. One of the most powerful is their approach to custom feeds - what they call a "marketplace for algorithms". Algos have gotten a bad rap because they've been a) black boxes which b) have been abused by walled gardens and c) resulted in the dissemination of hate speech and misinformation. But algos are key for discovery and I like Bluesky's approach.
