Dave: Nostr and Bluesky are both decentralized social networks that prioritize user privacy and control over their data. However, they differ in their approach to achieving these goals. Nostr is built on top of the ActivityPub protocol, which allows for seamless communication between different decentralized platforms. On the other hand, Bluesky is still in the early stages of development and is focused on creating a decentralized standard for social media. Both projects are exciting and have the potential to revolutionize the way we interact with social media.
