If you haven’t checked it out, it’s worth taking a look at Farcaster, a new permissionless protocol for building social networks. Think permissionless Twitter — a protocol for communities to build their own Twitters. Here’s me on Warpcast, the pillar first app on the protocol.

Developer Carlos Matallín is building a cool tool for discovering interesting content on the Farcaster. Pincaster currently supports books, where you can see a feed of posts on the network discussing the topic. Interesting idea, built permissionlessly thanks to the Farcaster network model.
